DST Scientific Institutions

Agharkar Research Institute, Pune

The Institute focuses on research in various branches of life sciences and is primarily engaged in developing microbial technologies for industrial waste treatment, identifying microbial products of industrial value, improvement of crops using conventional and molecular techniques, understanding the nutritional status of various socio-economic classes and devising appropriate interventions to study their effectiveness in combating nutritional problems. In addition, the basic studies include vertebrate developmental biology using chick model, fungal biology, biodiversity and bioprospecting.

Major Scientific Achievements & Highlights

  • A technology for producing biogas from oil cake generated during biodiesel production was developed and transferred to a start-up company in Pune. A collaborative agreement has been signed with a pharmaceutical company for contract research in the area of nano-biotechnology and nano-medicine. Four patents have been assigned to this company and incubation facility is being provided. An MoU has been signed with two chemical producing companies for joint research. Consultancy was provided to a private company on design parameters for anaerobic treatment of distillery waste. Two PCT applications and six Indian patents have been filed. One patent application on "Process for formulating repellent formulations for honeybees" has been accepted.
  • In studies aimed at identifying indicators to predict the risk for non-communicable diseases in urban affluent population, mid-arm circumference and neck circumference, apart from BMI, were found to be good indicators to predict the risk of hypertension. 2000 school children from low socio-economic class were studied for anthropometry and blood pressure. High prevalence of high Systolic Blood Pressure in them indicated 1) low body weights but relatively high body fat percentage and 2) developmental origin of adult diseases. Early-life under-nutrition and risks for adult diseases have shown that subjects who experienced stunting in early life (0-4 years) but had higher adult BMI showed higher risk for dislipidemia. To reduce the prevalence of anaemia among young rural girls, recipes of green leafy vegetables were standardized and demonstrated (Figure 10.1). This resulted in the reduction of prevalence of anaemia from 75 to 47%.

  • Amylolytic methanogenic strains with optimum amylolytic activity at 10ºC and cellulolytic strains with optimum cellulolytic activity at 20-25ºC were identified. Microbial ecology and biodiversity conservation programme led to: 1) genotyping of 50 alkaliphilic and haloalkaphilic bacteria isolated from Lonar lake, Buldana, Maharashtra, 2) developing of enrichments of psychrophilic methanogens from sediments of lakes in Leh and Ladakh, 3) identifying and isolating of two hydrogenotrophic and one acetoclastic methanogen from Lonar Lake, 4) isolating of thermophilic actinomycetes from Pashan Lake, Pune.
  • In plant biodiversity studies, chemical and DNA profiling was done for 'Chirayat', 'Kutki' and 'Shankhapushpi' complexes. A list of 38 endemic taxa occurring in Ratnagiri district was compiled. Nutraceutical studies on wild fruits of Ziziphus ('Ber') were found promising for prebiotic properties. Germplasm of Jatropha spp., Caesalpinia crista and Calophyllum inophyllum were collected from Western Maharashtra for evaluation. The oil content in Jatropha spp. varied between 31.48- 45.54%. Based on leads from Ayurvedic literature, the ethanol extract of Dalbergia lanceolaria bark was investigated for analgesic and anti-inflammatory activity. Plant extracts of Artemessia, Caesalpinia, Blumea and Wagatea spp. showed free radical scavenging activity and hepatoprotective activity against ethanol induced liver damage in liver slice culture.

  • In soybean improvement programme, mutant lines with high oleic acid content (>40%) were identified for improvement of oil quality. In 15 frontline demonstrations conducted on farmers' fields, improved practice recorded 31% higher seed yield than farmers' practices. 300 quintal breeder seed production was undertaken. In the wheat programme, recently released durum wheat variety MACS-3125 was the highest yielding durum in the zone (Figure 10.4). Bread wheat variety MACS-6145 possessing excellent grain quality and resistance was notified for rainfed cultivation in North-Eastern Zone. In studies on identification of markers linked to gluten strength in durum wheat, four protein markers, one STS marker for low molecular weight glutenin and two microsatellite markers showed significant association with the trait and explained 7- 34% variation in the trait value.

  • In fungal taxonomy, taxonomic accounts of 38 species of the lichen genus Graphis, including 20 species new to science have been prepared. In order to explore the possibility of PUFA production in submerged as well as solid-state fermentation, Thamnostylum sp. and Conidiobolus coronatus were screened using modified medium and in different incubation periods showed the presence of ALA. In-vitro sporulation in a non-sporulating endophytic fungus was carried out and six endophytic fungi were successfully identified.
Figure 10.5: Pieces of trisected hydra were irradiated separately at 500 J/M2 UV at 254 nm and regeneration was monitored over a period of 5 days. UV irradiation was found to induce ectopic foot formation in the middle pieces. Out of seven such cases, two showed duplicated feet at the usual location (a,b), two showed `twin' feet at the usual location (c,d), while the remaining three showed beginning of foot formation in the middle of the body column (e-g). Note an unusually large area showing foot-specific staining in the middle of the body column in addition to the normal foot in one case (g). The remaining 17 irradiated middle pieces did not exhibit ectopic foot formation (h)
  • In developmental biology, the effects of UVC and UVB on growth and pattern formation in hydra were studied. UV irradiation interfered with pattern formation in regenerating hydra, possibly by changing positional values, and promoted budding in intact hydra. This is the first report on induction of ectopic feet formation by UV in regenerating hydra and opens up the possibility of using UV irradiation as a tool to understand pattern formation in the enigmatic hydra (Figure 10.5). The results indicate that functional interaction between cytoskeletal components and cell surface architecture evolved early in evolution.
  • The Palaeobiology Group has established 1) a permineralized palm leaf Hyphaeneorachis nawargaoensis gen. et sp. nov., 2) the taxon Cocosoidocarpon indicum gen. et sp. nov. for a small sized coconut having 'three eyes', 3) a unique entire and matured soboliferous acaulescent palm Appamahabalea uhlii gen. et sp. nov. Aggluntinated foraminifera of Lower Cretaceous age were found with the lower Palaeolithic tools at Attirampakkam, Tamil Nadu. Palynological analysis of subsurface sediments from Hadi mangrove swamps, Sindhudurg, Maharashtra yielded information about the ecological shifts during the Early Holocene- Late Holocene Period.

The long term objective of CLCR is to design new liquid crystalline materials, carry out basic scientific research and to develop techniques for inventing new products and processes.

Major Scientific Achievements and Highlights

Activity-wise progress during the year is summarized below:

Photo-induced effects

Discovered a novel system in which a one-dimensionally solid and two-dimensionally liquid phase is induced and stabilized only in the presence of an actinic light. Explained the dynamic self assembly of such a structure on the basis of photoinduced nanophase segregation and frustrated spin gas model. Another important discovery was that of "A photonic dual-frequency addressable optical device" (Figure 10.6).

Figure 10.6: Template used and the optical storage pattern realized employing the dual-frequency photonic switch

Synthesis of materials with novel properties

Functionalized dimers based on a naturally available cholesterol moiety were synthesized in which mono, di and trialkoxy salicyladimine mesogenic segments were tethered to the cholesterol part with flexible alkoxy chains of different lengths. This covalent linkage through its parity and length plays a crucial role in determining the phase behaviour.

Confined geometry experiments

The delicate balance for self-assembly in liquid crystalline systems can be tipped when the material is confined in finite-size geometries. Our x-ray structural measurements showed that the extent of layering, the range of the layered phase, etc. can be tuned by the dimensions of the containing medium.

The Centre has been working on various topics of the basic and applied aspects of liquid crystals. Apart from designing and synthesizing new molecules with novel architectures exhibiting specifically targeted functionalities, the research work is being focused on many frontier and thrust areas of soft condensed matter science. A notable mention is that of photonics, in which light can be controlled by light as a stimulus. The Centre is at the forefront of research in this nascent field and has already demonstrated the importance of photo-driven isothermal phase transitions. On the application side, the Centre is not only working on devices based on new principles but also developing better driving technologies for the now ubiquitous Liquid Crystal Display devices. Emphasis is being given to nondisplay based applications also such as optical storage devices, anisotropic electric conductors, etc.

Other Initiatives

Free radical-promoted conjugate addition of activated bromo compounds was explored using titanocene(III) chloride as the radical initiator. Influence of alkoxy and acetoxy groups at the homoallylic position in facilitating RCM of 1, 6-dienes has been established. This phenomenon has been exploited for the synthesis of carbocyclic core of the nucleoside BCA.

Department of Theoretical Physics

Generic Einstein-Maxwell-Kalb-Ramond actions have been studied the area of high energy physics and cosmology and conditions derived under which they give rise to static spherically symmetric black hole solutions. Also, the large fine tunings of phase parameters of generic low energy supersymmetric models has been reduced significantly by identifying a cancellation in the flow of the bilinear Higgs coupling. In the area of condensed matter physics, a spin spin Hall effect has been predicted. The importance of taking into account the turbulent characteristics of the flow when accretion around a massive object is considered has been established.

Indian Institute of Astrophysics, Bangalore

The Indian Institute of Astrophysics (IIA) is devoted to the study of Astronomy, Astrophysics and allied topics. The headquarters were established in Bangalore and new field stations were established at Kavalur and Gauribidanur. During the last decade, the Institute has identified a superlative site for astronomy in the trans-Himalayan region of Ladakh and established the Indian Astronomical Observatory (IAO) at an altitude of 4500 m on Mt Saraswati, Hanle. Initially the observatory is equipped with the 2-m Himalayan Chandra Telescope (HCT) operated remotely from the Centre for Research & Education in Science & Technology (CREST), the newly set up campus of IIA in Bangalore.

During the year 2005, a total of 10 research papers have appeared in leading international journals, apart from papers presented at conference proceedings and results disseminated through international circulars. During 2005, the telescope was equipped with an autoguider to track objects precisely over long durations. The Institute has also expanded its operations into Space Astronomy through the UltraViolet Imaging Telescope (UVIT) and the Indo-Israeli TAUVEX payloads, and into the ground153 based gamma-ray astronomy collaboratively with the Tata Institute of Fundamental Research (TIFR), Mumbai, and the Bhabha Atomic Research Centre (BARC), Mumbai.

Research in a broad range of topics continued during the current year in the areas of observational astrophysics.

Major Scientific Achievements and Highlights

The installation of two units of the HimAlayan Gamma Ray (HAGAR) telescope array at IAO, Hanle was completed (Figure 10.7). HAGAR consists of seven such units located at the centre and corners of a hexagon of 50 m sides, situated in the Nilamkhul Plain (4300 m above msl) at the base of Mt Saraswati. Each unit consists of 7 light collectors of 90-cm diameter fixed on a single mount. The detection technique maps the cone of Cerenkov radiation resulting from the interaction of the celestial gamma-rays with the earth's atmosphere. The designing of the UVIT payload has progressed well and the Preliminary Design Review is scheduled in February 2006. UVIT, consisting of two co-aligned 40-cm diameter ultraviolet imaging telescopes, forms a part of the multi-wavelength astronomy ASTROSAT Mission scheduled to be launched by ISRO in early 2007. IIA is also participating in the Indo-Israeli ultraviolet imaging experiment (TAUVEX), which consists of three co-aligned 20-cm diameter telescopes. TAUVEX hardware is built by El-Op, Israel, whereas the software for data acquisition and reduction is developed by IIA. The payload is scheduled to be launched by ISRO on GSAT-4 in the year 2006.


Figure 10.7: One of the two units of the HimAlayan Gamma Ray (HAGAR) Telescope array installed at the IAO, Hanle. The telescope will have a total of seven units, one located at the centre and six at the corners of a hexagon of 50 m sides

Fabrication of the eight-stage modulation scheme polarimeter for the Vainu Bappu Observatory is in progress. Work on building a WARM (White light Active Region Monitor) telescope for imaging of the Sun on high temporal basis is in progress. Designing of mechanical layout of the coelostat and its electronic control drive is completed. Imaging of the Sun on fast mode is expected to throw light on the pre-flare build up of non-potential energy in an active region.

Sun and the Solar System

The program for digitization of photographic data at Kodaikanal Observatory has been in progress. Recent observations indicate that line intensities in coronal holes are affected in the lower transition region and even in the chromosphere. IIA used the daily Calcium K filtergrams from Kodaikanal to probe the signatures of coronal holes in the chromosphere. Analysis of the data obtained from Brazil during the solar eclipse of 3rd November, 1994 at 1.5 GHz, showed that a source of angular size of 12 arcsec was associated with the active region AR 7798.

Investigations of the dust morphology of comet 2001Q4 have been completed. The VBO data clearly shows the location of the dust plume that occured about 9 hours after the impact.

Stars and Stellar Systems

An analysis of ultraviolet spectra of Extreme Helium Stars has provided new clues to their origins. A new photometric method was derived for measuring the distances to interstellar clouds that uses multi-band (B,V,R,I,J,H,K) photometry of stars in the region of the clouds and an extinction law. This method was used to determine distances to 9 interstellar clouds to an accuracy of about 15 - 20 %. Photometric observations to detect the halo of the LMC were obtained using the 4.0m and 1.0m telescopes at CTIO, Chile in October 2005. Photometric observations of 8 candidate old open clusters in our Galaxy were obtained using the HCT in August 2005. Classical novae V1663 Aql, V476 Sct and V477 Sct, three new novae in outburst discovered in 2005 were spectroscopically monitored using the 2m HCT (Figure 10.8). In addition, an extragalactic nova, Nova M31 #14 was also monitored spectroscopically. An Indo-Japanese collaboration for studies of low redshift core collapse supernovae was established. The peculiar type Ib supernova SN 2005bf was observed around maximum using the 2-m HCT.


Figure 10.8: M 51, a spiral galaxy in which a supernova SN 2005cs erupted. This image was obtained in the R band with the 2m HCT. The supernova which is a sub-luminous Type IIp has been extensively followed by us both photo-metrically and spectroscopically

A programme for coordinated, two-station monitoring of radio quiet quasars (RQQs) has been going on with NCRA. Optical monitoring of these objects is being done using the 2m HCT and the 1m ST of ARIES. Scientists have been working on radio pulsars-theory and observations. From the observed pulsar profiles, methods for estimating the rotation effects such as aberration-retardation on the phase shift of pulse components have been developed.

Non-accelerator Particle Physics

A variety of topics in non-accelerator particle physics and atomic astrophysics were studied. Investigations were conducted on two important probes of physics beyond the Standard Model- parity non-conservation (PNC) in atoms and electric dipole moments (EDMs) of atoms. The work on PNC in Ba + has reached an accuracy of less than one percent. Research was conducted on a new approach to the high precision calculation of ground and excited state atomic properties that are relevant in the study of fundamental symmetries and different astrophysical processes.

Theoretical Astrophysics

The analytical formulae derived for the scattering phase matrix have been studied in the limiting cases of Zeeman and Hanle regimes in the two level case with angular momentum 1 for the upper level and 0 for the lower level. Relativistic Fock-space Coupled Cluster and multi-reference many body perturbation methods were developed and applied to compute transition energies and related properties for closed shell atoms. A scheme was also developed to compute P,T-odd interaction constant for diatomic polar molecule containing heavy elements (YbF and BaF).

Other Initiatives

A total of 73 research publications have appeared in research journals, and 38 in conference proceedings. The observational and infrastructure facilities at all the field stations were strengthened further. Special mention may be made of the installation of a 30 kWp solar photovoltaic array at Hanle to supply electric power to the HimAlayan Gamma Ray (HAGAR) telescope project under development.

An Indo-Chinese workshop on 'Recent Advances in Solar Physics' was organized in November 2005. Considerable progress was achieved in planning new solar initiatives at IAO, Hanle, and in the preparations for coordinated activities during the International Heliophysical Year (IHY-2007).

A Memorandum of Understanding is in preparation for a larger project of Major Atmospheric Cerenkov Experiment (MACE) coordinated by BARC in collaboration with TIFR and IIA. A twoday mini-workshop was held in IIA, Bangalore in November to discuss the Gamma Ray Astronomy and future prospects in the country.

21 young scientists are being trained in the Institute towards their Ph.D. degrees; another four have submitted their Ph.D. thesis during the current year. The members of the Institute continued their teaching activities in the Institute, Joint Astronomy Program at the Indian Institute of Science, Bangalore University and other centres. Several scientists offered advanced level courses to students in universities and trained them in Astronomy and Astrophysics. The Human Resource Development is also continuing through the research and engineer trainee programmes, summer project students programme, degree project programme, visiting Ph.D. students programme, etc.
 
Indian Institute Of Geomagnetism, New Panvel, Mumbai

The main areas of research at the Indian Institute of Geomagnetism (IIG) are: Observatories and Data Analysis, Upper Atmospheric Sciences, and Solid Earth Geomagnetism. The instrumentation division of IIG is involved in development and maintenance of various instruments used for observations in the above areas.

Major Scientific Achievements and Highlights

Observatories and Data Analysis

The Institute continued to operate nine magnetic observatories at different locations in the country, where magnetic field variations were continuously recorded. An Induction Coil Magnetometer was deployed at IIG's Laboraory at Allahabad.

Ranges and amplitudes computed for magnetic storms were classified with reference to their occurrence features at Indian stations, and forwarded to World Data Centre (WDC), Colorado, for inclusion in the Geophysical Data Bulletin. The final definitive data for Alibag up to December 2004 were forwarded to the Danish Meteorological Institute, for inclusion in the Annual CD-ROM brought out by them. Eighteen magnetic compasses of Landing and Datum type, received from Indian Navy, were calibrated at magnetic observatory Alibag.

A comparative study of secular variation of the main geomagnetic field, at Alibag (10o N dipole latitude) and Indian Antarctic station, Maitri (67o S dipole latitude) showed that at Alibag no significant 156 DST ANNUAL REPORT 2005-2006 decrease was seen in the last century, whereas at Maitri the magnetic field decreased by about 2500 nT in the last two decades (Figure 10.9).

Magnetic field calculated using IGRF model (?) and linear fits (?) at the two locations are also shown. redistribution of water vapour that compete with the dominant migrating tide to induce the observed inter-annual variability in the diurnal tide found during the El Nino-La Nina years of 1997-1999.

Upper Atmospheric Sciences

A two-dimensional electrostatic particle code using curvilinear coordinates is being developed to study the auroral electron acceleration mechanism. Simultaneous observations of equatorial spread F (ESF) irregularities made using 18 MHz HF radar at Trivandrum and two spaced receivers at Tirunelveli that recorded ionospheric scintillations on a 244 MHz radio wave signal transmitted from a geostationary satellite, were used to understand the evolution of spatial structure in ESF irregularities in the post-sunset equatorial ionosphere.

Analysis of night airglow data of OH (8,3), OH(6,2) and OH(7,2) bands, from Kolhapur, was continued to infer the temperature of the mesosphere and validate atmospheric models. An airglow photometer to monitor F-region atomic oxygen emission at 630.0 nm was made operational at the Equatorial Geophysical Research Laboratory (EGRL) of IIG at Tirunelveli. Analysis and interpretation of existing datasets from 2001-2004 of atmospheric air-earth current measurement at the Indian Antarctic Station, Maitri, was carried out for understanding some features of the global electric circuit. Instruments and techniques were developed to measure the atmospheric conduction current.

Long-term MLT radar observations of the diurnal tide at 86 km over Tirunelveli during the years 1993-2004 exhibited a pronounced annual cycle that was modulated on inter-annual time scales. Removal of composite seasonal cycle yielded 'anomalies' in the diurnal tide over Tirunelveli that were compared with the quasibiennial oscillation (QBO) wind at 30 hPa derived using the Singapore radiosonde data and satellite derived Outgoing Longwave Radiation (OLR) anomalies over this region (Figure 10.10). Lower atmospheric large-scale convective systems originating in the southern tropical latitudes over the western Pacific region in response to the El Nino Southern Oscillation (ENSO) possibly facilitate excitation of non-migrating tides through latent heat release or large-scale

Solid Earth Geomagnetism

In magneto-telluric (MT) surveys conducted in the Andaman region; a major NNE-SSW trending thrust zone, with eastward dip of about 60 degrees, was delineated. MT studies in the Lower Assam valley and Shillong Plateau identified thrust zones corresponding to Oldham and Dauki faults. Analysis of MT data collected in the Kaladgi basin, shows a strike direction of N45°W which is close to the major geological strike direction of the study area. Preliminary results of the Geomagnetic depth sounding data over Andaman suggest presence of conductivity structure between Car Nicobar Islands and Little Andamans.

Curie isotherm depths were estimated from aeromagnetic anomaly map over certain regions in India (Figure 10.11). The mobile belts had shallower Curie isotherm when compared to the cratons. The depth estimates matched those calculated from the MF4 lithospheric model of Champ satellite.

Third repeat geomagnetic survey conducted in Jabalpur-Kosamghat area observed higher annual changes in the total magnetic fields along the identified Satpura conductor could be due to fluids trapped in the crust.

The environmental magnetism group carried out field surveys of Mumbai and Navi Mumbai for studying pollution characteristics using magnetic measurements. Analysis of Loess samples of central higher Himalaya has yielded a monsoon climate record for the past 20Ka (Figure 10.12).

Figure 10.12: Environmental mineral magnetic proxy climate record over Indian subcontinent: Climate sensitive mineral magnetic ratio called S-ratio reflects accurately the palaeoclimatic changes over the entire Indian subcontinent. High magnetic ratios corresponding to high 'magnetite to haematite' ratios are found in the wet spell sediments and vice versa. The S-ratio record of the Himalayan Dhakuri loess clearly outlines key climatic events over the past 20 ka revealing step-wise improvement in SW monsoon since Last Glacial Maximum (LGM), culminating in its establishment around 9 ka.

Palaeomagnetic investigations were carried out on the dyke samples of Bundelkhand craton, Nasik and Kutch. Initial phase of Deccan magmatism was identified in these studies. IIG's first global positioning system (GPS) campaign in Andaman and Nicobar Islands was carried out. GPS field campaigns were also undertaken in Garhwal and Kumaon regions of Middle Himalayas to study crustal motion in these regions.

Other Initiatives

Indian Institute of Tropical Meteorology, Pune

The Indian Institute of Tropical Meteorology functions as a National Centre for basic and applied research in Tropical Meteorology. Its primary functions are to promote, guide and conduct research in the field of Meteorology and Atmospheric Sciences in all its aspects with special reference to the tropics and sub-tropics.

Major Scientific Achievements and Highlights

The highlights of the progress made in the on-going programmes during the year are summarized below:

Extended Range Weather Prediction Research

For seasonal prediction of Indian summer monsoon rainfall, a Neural Network Model was developed using De-Bilt January temperature anomaly, sea ice extent anomaly in Antarctic in winter, Northern Atlantic Oscillation (NAO) in the month of April and tendency of Effective Strength Index (ESI), from January to April. The model was tested for the period 2001 - 2004. The model well predicted the large deficient years 2002 and 2004. The Heidk Skill score for the model was found to be 0.7. By using the Neural Network Model, seasonal forecast for 2005 was prepared and was found to be + 4%. Simulations of monsoon 2005 from both the Centre for Ocean Land Atmospheric Studies (COLA) and Portable Unified Modes (PUM) models indicated below normal seasonal monsoon rainfall over the Indian region.

Seasonal Prediction of Indian Summer Monsoon

Experimental forecast of the seasonal total (June - September 2005) of the Indian Summer Monsoon Rainfall (ISMR) for the country as a whole was attempted, by using predictors selected only from sea surface temperature (SST) field, Empirical forecast from this method can be obtained three months in advance. The forecast obtained for the year 2005 ISMR was found to be 12% below normal.

Studies of Monsoons and Tropical Weather System

A simple regression equation was developed to predict the date of onset of Indian summer monsoon over Kerala. The equation was used to predict the date of onset over Kerala for monsoon 2005, by using the information of daily thunderstorm activity over south peninsular India during April 2005. The equation suggested 5 June as onset date for the year 2005 which was later observed to be the same.

Dendroclimatic Analysis over Western Himalaya

Ring width data of Cedrus deodara D. Don [Himalayan Cedar], collected from five locations near Gangotri, Uttaranchal Himalaya were analyzed. Noticeable feature of all the series was found to be unprecedented surge in tree growth after around A.D 1930. Such anomalous behavior was not observed prior to A. D. 1930 which may be possible due to the effect of enhanced winter warmth. Analysis of surface air temperature over Western Himalaya indicated significant increasing trend in maximum and mean temperature during 20th century. More warming during recent four decades was also noticed in minimum temperatures in the region.

Hydrometeorological Studies of River Basins

Under the project entitled Preparation of generalized PMP Atlases over the Krishna and Indus river basins, based on a long period daily rainfall data of 570 stations in and around the Krishna river basin 8 to 10 severe rainstorms over each of 5 sub-catchments of the basin were analysed by Depth- Duration (DD) or Depth-Area-Duration (DAD) depending upon orography of the region.

Heliospheric Current and Indian Summer Monsoon

Actual rainfall data were bifurcated into two groups (i) Rainfall falling under (-, +) crossing events and (ii) Rainfall falling under (+,-) crossing events. Indian summer monsoon rainfall in all the states was found to have an in phase relation with (-, +) crossing events. i.e. magnetic sector boundary polarity towards the sun (heliospheric current) followed by more summer monsoon rainfall activity.

Cyclonic Storms / Depressions and Magnetic Sector Boundary Events

A study was carried out to examine the relationship between number of cyclonic storms and depressions forming over tropical seas and Magnetic Sector Boundary (MSB) Crossing Events. Studies revealed that number of cyclonic storms and depressions were found to have in-phase relation in June and September and out-of-phase relation in October and December with (-,+) and (+,-) MSB crossing events, respectively.

Impact of Tsunami on Surface Ozone

The unusual changes were observed in ozone and NOx concentrations after the giant tsunami waves struck at Tranquebar, a tropical rural coastal site on the east coast (the Bay of Bengal) of southeast India on 26 December 2004. The average maximum of O3 concentration was found to be unusually reduced by 45% at noon and minimum of O3 concentration increased by 164% in the morning due to tsunami impact. The unusual diurnal variation of O3 was observed up to 19 January 2005 after tsunami impact due to changes in the photochemical production and destruction of O3. Similarly average daytime and nighttime NOx also increased from 5.6 ± 0.35 to 9.5 ± 0.66 ppbv and 6.5 ± 0.22 to 9.2 ± 0.34 ppbv with 1 ó standard deviation due to tsunami impact.

Whistler Studies during Magnetospheric Disturbances

Whistler triggered emission at a low latitude station during moderate magnetic storm activity was explained using the Doppler-shifted cyclotron resonance interaction between whistler mode wave and counter streaming energetic electrons. The estimated wave magnetic field, transverse resonant current and interaction length were found to increase during disturbed magnetospheric conditions while the number of energetic electrons participating in resonance processes under normal and disturbed conditions remains approximately the same.

Analysis of ARMEX Data

Measurement of ion concentration and electric conductivity during the ARMEX showed that the value of polar conductivity was much higher during the monsoon than the pre-monsoon season.
