Abstract

The BEHR OMI NO2 product reprocesses tropospheric NO2 columns from the Ozone Monitoring Instrument (OMI) satellite using high resolution a priori NO2 profiles, surface reflectivity, and surface elevation data. This product uses NO2 profiles for the day retrieved, simulated by the WRF-Chem model at 12 km spatial resolution. The use of high spatial resolution NO2 profiles has been shown to better resolve urban/rural differences in NO2 column densities, and the use of day-to-day (rather than monthly average) profiles is especially important in applications that preferentially select observations upwind or downwind of a NOx source.

Methods

The methods for the BEHR product are described in detail in Laughner et al. (in prep). 

Usage Notes

Each month of BEHR data is stored as a .tar.gz file (i.e. a tar archive compressed with gzip). These can be decompressed using 7zip or (on Mac/Linux) the command "tar -xzvf <filename>", e.g. "tar -xzvf OMI_BEHR-DAILY_US_v3-0A_200501.tar.gz" will expand OMI_BEHR-DAILY_US_v3-0A_200501.tar.gz
