High-resolution OMI NO2 for mid-Atlantic USA: June & July 2008 - 2012

Tropospheric NO2 vertical column contents from OMI during June & July 2008 - 2012 in the mid-Atlantic.
There are two file groups:
1. OMI NO2 processed with air mass factors using observationally-constrained NO2 profiles from a high-resolution regional model.
2. OMI NO2 processed with air mass factors using observationally-constrained NO2 profiles from a high-resolution regional model, which are further downscaled to 1.33 km resolution using model variability in the regional model.
