Dr. Jethva has spent more than 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 (2008) 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. During his postdoctoral fellowship (2009-2011) at the Hampton University, Hampton, VA, USA, he evaluated the Ozone Monitoring Instrument (OMI) operational aerosol products and provided critical suggestions towards improving the algorithm. Since 2011 and under the NASA/USRA’s GESTAR program, and now with Morgan State University as a senior research scientist under GESTAR-II, 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, DSCOVR-EPIC, and S5p-TropOMI observations.
