Abstract:
We quantify spatial and temporal variability of both in-situ mixing ratios and column integrated O3, NO2, CO, SO2, and HCHO during the four deployments of the NASA Earth Venture mission DISCOVER-AQ (Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality). Using structure function analyses, we compare simulated variability of output from the regional chemical models WRF/Chem and CMAQ with variability observed during the campaigns. The Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument will be the first NASA mission to make atmospheric composition observations from geostationary orbit and partially fulfills the goals of the Geostationary Coastal and Air Pollution Events (GEO-CAPE) mission. We compare both observed and simulated variability to the precision requirements defined by the science traceability matrices of these space-borne missions to explore how they relate to the science questions they are tasked to address.
