Remote-Sensing of Surface-Level Ozone Sensitivity to Nitrogen Oxides and Volatile Organic Compound
Dr. Geddes is a Co-Investigator on a NASA grant that has been selected for funding! The total award is for $717,304 and is being led by a collaborator from the Universities Space Research Association (USRA) at NASA Ames Research Center (Dr. Sajeev Phillip), and involves other collaborators at NCAR, NASA Goddard Space Flight Center, the Harvard-Smithsonian Center for Astrophysics, and NASA Langley.
Tropospheric ozone (O3) is a harmful pollutant and detrimental to surface air quality having negative impacts on human health and vegetation, and its formation depends on the relative abundance of precursor species such as NOx and VOCs. Surface O3 pollution mitigation policies strongly rely on a clear understanding of the atmospheric chemical processes involving O3, NOx, and VOCs. The overarching science goal of this project is to exploit the untapped potential of 15+ years of OMI HCHO and NO2 retrievals to improve the fundamental understanding of O3-NOx-VOC photochemistry.
