Project Ti tle: 50M Instruments Meteorological Tower Year: 2010 Funding agency: Indira Gandhi Centre for Atomic Energy (IGCAR), Kalpakkam Principal Investigators: Dr.B. Sheela Rani, Dr.P.Sardar Maran The 50 Metre tower at Sathyabama Institute of Science and Technology has multilevel sensors for all the basic atmospheric parameters like wind speed and direction, temperature, relative humidity, pressure, rainfall and nuclear radiation. The data from this tower will be used in real time for site-specific, on-line dispersion modeling and prediction at IGCAR as well as for basic studies on mesoscale sea-land breeze circulation. The real time weather data is utilized for several student projects in interdisciplinary level at Sathyabama Institute of Science and Technology.
Project Title: MICROMETEOROLOGICAL WIND FIELD MEASUREMENT CAMPAIGN AT Sathyabama Institute of Science and Technology FOR VALIDATION OF ATMOSPHERIC FLOW MODELS DURING ROUND ROBIN EXERCISE (RRE-I) Year: 2011 Funding agency: Indira Gandhi Centre for Atomic Energy (IGCAR), Kalpakkam Principal Investigators: Dr.B.Sheela Rani, Dr.P.Sardar Maran The RSD, IGCAR has established a number of meteorological observational networks for the atmospheric / radiological dispersion studies over more than 2 decades. It is very important that data from the network is preserved in a data server and be reported in standard formats for any past or present query times. Hence as part of our collaborative programme, it is proposed to develop a web-based (online) data query and visualization software to meet the above requirement

Project Title: Assessment of blue carbon stock in the mangroves ecosystems of Tamilnadu Year: 2015 Funding agency: Department of Science & Technology (DST), New Delhi. Principal Investigators: Dr. B. Prabhu Dass Batvari To study the changes in spatial extent of mangroves ecosystem in Tamil Nadu. .A carbon baseline assessment that will estimate the stocks of carbon for mangroves ecosystems, and rate of carbon sequestration associated with mangrove afforestation.
Project Title: Late Holocene tectonic land level changes and tsunamis: Comparison between Muthupet Lagoon, Bay of Bengal and Rocky Island Creek, South Andaman, Indian Ocean Year: 2016 Funding agency DST-SERB, New Delhi Principal Investigators: Dr.P.M.Velmurugan The complete multi-disciplinary approach to the core sediments of Muthupet lagoon, Bay of Bengal and Rocky Island Creek, South Andaman is planned in order to bring out the Late Holocene tectonic land-level changes of these regions from the sedimentary records. Undisturbed marshy and estuarine sediments are chosen for the present research work as they provide sedimentary deposits of both terrigenous and marine origin. Sedimentological, stratigraphic and geochemical data record abrupt land elevation change, coastal subsidence, and changes in the salinity of these regions that provide vital clue in the recognition and evaluation of tectonic land-level changes that have happen during the late Holocene period.
Project Title: Development of Inversion algorithm for retrieval of atmospheric parameters from atmospheric lidar data Year: 2016 Funding agency: Indian Space Research Organization (ISRO),Department of Space, Govt. of India. Principal Investigators: Dr.P.Sardar Maran The Rayleigh lidar located at National Atmospheric Research Laboratory, Gadanki, Andhra Pradesh(13.5_ N, 79.2_ E), uses an Nd: YAG laser and has maximum energy of 600 mJ per pulse at 532 nm, pulse repetition frequency of 50 Hz and a pulse width of 7 ns. The lidar is operated with an altitude resolution of 300m and pulse repetition frequency of 20 Hz. The receiver employs a Newtonian telescope with primary mirror of effective diameter of 75 cm for the temperature measurement in the 30 to 80 km altitude region. In this research improvement of Signal to Noise Ratio (SNR) to increase the height coverage of the lidar system was developed with ANFIS and Wavelet network.
