Head, Land and Atmospheric Physics Division (LAPD), Earth and Climate Sciences Area (ECSA), National Remote Sensing Centre (NRSC), Hyderabad, India.
He is currently heading Climate Studies Group of Earth and Climate Studies Area at the National Remote Sensing Centre (NRSC), Hyderabad. He was Assistant Project Scientist at Scripps Institution of Oceanography, UCSD, US (2001-2010) and Professor at Indian Institute of Space Science and Technology (IIST), India (2010-2016). His major achievements are in the fields of aerosol-cloud-radiation-climate studies, land surface processes, instrumented-UAVs for atmosphere-climate studies, retrieval and validation of geophysical products, climate change and mitigation. He is involved in use of lithe ght-weight UAVs for making measurements of albedo, aerosol-cloud-albedo interactions, and atmospheric deposition of solar radiation fluxes. He led a team that used the INSAT-3D satellite to determine the strength of aerosol-cloud interaction on cloud fraction and cloud top temperature under the anthropogenic polluted conditions of Arabain Sea. Currently, he is working on geophysical parameter retrieval for Essential Climate Variables from Indian Earth Observation satellites. He is representing ISRO at CEOS’s Atmospheric Composition Virtual Constellation (AC-VC).
