Summary

Description

The OMI science team produces two Level-3 Aura/OMI Global Aerosol Data Products OMAERUVd (1deg Lat/Lon grids) and OMAEROe (0.25deg Lat/Lon grids). The OMAERUVd product is based on the Level-2 OMAERUV product that uses the near-UV algorithm whereas the OMAERO product is based on the multi-wavelength algorithm that uses up to 20 wavelength bands between 331 nm and 500 nm. OMAERO retrieval algorithm is developed by the KNMI OMI Team Scientists. Drs. Deborah Stein-Zweers, Martin Sneep and Pepijn Veefkind are now the key investigators of this product. (The shortname for this Level-3 Global Gridded Aerosol Product is OMAEROe_V003) The Level-3 OMAEROe product selects best aerosol value from the Leve2G good quality data that are reported in each grid. The selection criteria is based on the shortest optical path length (=Secant of solar zenith angle+Secant of view zenith angle). OMAEROe files are stored in EOS Hierarchical Data Format (HDF-EOS5). Each file contains daily data from approximately 15 orbits. The maximum file size for the OMAEROe data product is about 7 Mbytes.
