These data are available for users wanting to generate custom Level-2 products using the Collection 2 surface reflectance and surface temperature algorithms. It is not necessary for users to download the atmospheric auxiliary data for use with Collection 2 Level-2 products. 

The USGS Landsat Image Assessment System (IAS) repackages the TOMS and OMI ozone product text files and creates daily HDF files that contain an “ozone” Scientific Data Set (SDS), stored as 16-bit integers. The daily file is a global dataset with 1.25° x 1° lat/long grids or 1° x 1° lat/long grids, depending on the source of the data, which is denoted in the “Platform” attribute. The repackaged file also contains “lat” and “lon” SDSs that contain the latitude and longitude value along each grid axis.
