    Dr. Jethva has spent almost about a decade in learning, developing, and validating the satellite-based aerosol retrieval from different sensors on board NASA’s EOS satellites. His Ph.D. thesis investigation was focused on analyzing aerosol patterns using ground and satellite measurements and suggesting improvements to the 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 is responsible to 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 OMI, MODIS, And DSCOVR-EPIC observations.
