Satellite Data to Enhance Ozone Modeling
Satellites provide opportunities to remotely sense atmospheric data with far greater spatial coverage than is possible from ground-based observational networks. Our research is exploring the incorporation of two types of data -- photolysis rates based on GOES satellite measurements of clouds, and NO2 measurements from the OMI satellite -- to enhance photochemical modeling of ground-level ozone. Inverse modeling will use the satellite observations of NO2 columns to adjust emissions inventories of nitrogen oxides. We will investigate how the resulting satellite-adjusted photolysis rates and NOx emission inventories could influence sensitivity modeling of the responsiveness of ground-level ozone to emission control measures in Texas.
