OMI/Aura Sulphur Dioxide (SO2) Noise Reduced Total Column 1-orbit L2 Swath 13x24 km V004 (OMSO2NR)

The OMI/Aura Sulphur Dioxide (SO2) Noise Reduced Total Column 1-orbit L2 Swath 13x24 km (OMSO2NR) data product is a research product made public. 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 OMSO2NR product is Can Li. The OMSO2NR files are stored in the version 5 Hierarchical Data Format (HDF5). 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.
