OMI/Aura Nitrogen Dioxide (NO2) Total and Tropospheric Column 1-orbit L2 Swath 13x24 km V003 (OMNO2) at GES DISC
The Version 3 Aura Ozone Monitoring Instrument (OMI) Nitrogen Dioxide (NO2) Standard Product (OMNO2) is now available from the NASA Goddard Earth Sciences Data and Information Services Center. The major improvements include: (1) an improved spectral fitting algorithm for retrieving slant column densities, including the use of monthly mean solar spectral irradiances; (2) improved resolution (1 degree latitude and 1.25 degree longitude) a priori NO2 profiles from Global Modeling Initiative chemistry-transport model with yearly varying emissions. The improvements are described in the updated OMNO2 readme document (see Documentation). The OMNO2 contains slant column NO2 (total amount along the average optical path from the sun into the atmosphere, and then toward the satellite), the total NO2 vertical column density (VCD), the stratospheric and tropospheric VCDs, scattering weights, cloud radiative fraction and optical centroid pressure, and other ancillary data. The short name for this Level-2 OMI total column NO2 product is OMNO2. The algorithm leads for this product are NASA OMI scientist Dr. Nickolay A. Krotkov and KNMI Scientist Dr. Pepijn J. Veefkind. The OMNO2 files are stored in the version 5 EOS Hierarchical Data Format (HDF-EOS5). Each file contains data from the day lit portion of an orbit (~53 minutes). There are approximately 14 orbits per day. The maximum file size for the OMNO2 is ~23 MB.
