Berkeley High Resolution (BEHR) OMI NO2 - Native pixels, monthly profiles

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. Given the computational cost of simulating daily 12
km resolution profiles over the continental US and the challenge of
simulating individual lightning events accuractly, we still provide a
product using monthly average NO2 profiles.
