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.
The methods for the BEHR product are described in detail in Laughner et
al. (in prep).
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 In addition to downloading
the full dataset or manually downloading individual files, a Python
program is available at https://github.com/CohenBerkeleyLab/BEHRDownloader
that can perform bulk downloads of a subset of the files, as well as
automatically uncompress the tar files. See the Readme in that repo for
further usage information. For details on best practices for using the
BEHR data, see the user guide PDF included in this repository.
