Dear All,
i am Atmospheric Scientist,
Qualification - B.E. (Instrumentation),M.Tech (Atmospheric Science).
Brief description of research activity
I am working in the Program “Basic physics of tropics through observations (Aerosol and Climate Studies) in specific area of Remote Sensing of atmospheric aerosols and gases using Active and Passive techniques. The main objective is to develop the experimental technique for studying impact of aerosols and trace gases using Lidar (active) and radiometric (passive) techniques and the studies connected with vertical distributions of aerosols and columnar aerosol and trace gas, optical depths utilizing the observations from computer-controlled, bistatic and monostatic lidar (Argon ion, Eximer, Co2, Raman and DPMPL lidar), Solar radiometers (Microtops II Sun photometer, spectroradiometer) and Radiation (Pyaranometer & Pyarziometer).
I was a member of 24th (2004-05) & 26th (2006-07) Indian Antarctica Expedition in connection with scientific research project entitled “Direct Radiative Forcing due to Aerosols and Precursor Gases Over Antarctic Region”, PI- P.C.S. Devara and Co-PI- S. M. Sonbawne submitted by the Institute.
currently working on A scientific research project entitled “Role of Aerosols and precursor gases in direct radiative forcing over Arctic Region” at Ny Alusend, as PI - S. M. Sonbawne and Co-PI- P.C.S. Devara, Dr. P. D. Safai, Dr. P.S. Salvekar, Dr. P. R. C. Rahul.
I do work for the maintenance of experimental facility to the Laser Laboratory at the Institute, also setting-up instrument and carry out modification to them as per the experimental requirement, and developments of data retrieval techniques, in this connection:
Very recently the new data acquisition system (dual channel) MCS based is installed for the Eximer lidar system to improve the data quality and the receiving power for the vertical profiling of ozone up to the stratosphere.
