Jinkyul Choi specializes in combining satellite observations with air quality models to quantify emissions from both human-made and natural sources. Her work provides valuable insights for researchers, policymakers, and the public in addressing air quality and health challenges. During her Ph.D., she focused on constraining volatile organic compound (VOC) emissions. She used inverse modeling techniques on satellite measurements of formaldehyde from the Ozone Monitoring Instrument (OMI) and Ozone Mapping and Profiler Suite (OMPS), as well as isoprene data from the Cross-Track Infrared Sounder (CrIS). At JPL, she plans to expand her research by synthesizing multi-constituent satellite observations. Her goal is to enhance our understanding of key air pollutants and VOCs, exploring their complex atmospheric interactions and health impacts.
