OMI/Aura Sulphur Dioxide (SO2) Total Column 1-orbit L2 Swath 13x24 km V004 NRT
Listed in NASA Data Portal
The OMI/Aura Sulphur Dioxide (SO2) Total Column 1-orbit L2 Swath 13x24 km NRT (OMSO2) data product has been updated with a principal component analysis (PCA)-based algorithm (v2) with new SO2 Jacobian lookup tables and a priori profiles that significantly improve retrievals for anthropogenic SO2.
Description
The data files (or granules) contain different estimates of the vertical column density (VCD) of SO2 depending on the users investigating anthropogenic or volcanic sources.
Files also contain quality flags, geolocation and other ancillary information. The lead scientist for the OMSO2 product is Can Li.\n\nThe OMSO2 files are stored in the version 5 EOS Hierarchical Data Format (HDF-EOS5). Each file contains data from the daylit half of an orbit (~53 minutes).

There are approximately 14 orbits per day. The resolution of the data is 13x24 km2 at nadir, with a swath width of 2600 km and 60 pixels per scan line every 2 seconds. \nFor the full set of Aura products and other atmospheric composition data available from the GES DISC, please see the links below. disc.sci.gsfc.nasa.gov/Aura/ disc.gsfc.nasa.gov/acdisc/", "VersionDescription": "Collection 004 for Near Real TIme
