Dr. Jethva has developed an expertise in analyzing and validating the satellite-based aerosol retrieval techniques from different sensors onboard NASA’s EOS satellites. His Ph.D. thesis investigation was focused on analyzing aerosol patterns using ground and satellite measurements and suggesting improvements to NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) operational aerosol retrieval over the Indian region. His postdoctoral fellowship at Hampton University, Hampton, VA, USA, during 2009–2011 was dedicated to the evaluation of the Ozone Monitoring Instrument (OMI) operational aerosol products and providing suggestions for the possible improvements in the algorithm. Under the NASA/USRA’s GESTAR program, he has been responsible for the upkeep, maintain, and validate the OMI aerosol product as well as develop innovative algorithms for characterizing aerosols above clouds. He has played a lead role in developing the near-UV and visible-based techniques for the quantitative retrieval of the above-cloud aerosols from satellite sensors OMI, MODIS, and DSCOVR-EPIC observations.
