Ozone data products are available for the Total Ozone Mapping Spectrometer (TOMS) instruments and for the Ozone Monitoring Instrument (OMI), and are used in the surface reflectance algorithm for Landsat 4-7 data. Different sources are used for different date range.
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.

MODIS Fused C2 is a fused product of water vapor and ozone data used to process Landsat Collection 2 Level-2 products. This product contains four MODIS data sets: MODIS Aerosol Optical Thickness Daily Climate Modeling Grid (MOD09CMA and MYD09CMA) and MODIS SR Daily Climate Modeling Grid (MOD09CMG and MYD09CMG).USGS EROS Archive - Landsat - Atmospheric Auxiliary Data - MERRA-2 C2
Modern Era Retrospective analysis for Research and Applications Version 2 (MERRA-2) is a NASA atmospheric reanalysis that provides data beginning in 1980. MERRA-2 provides atmospheric data that are used as input to the radiative transfer model used to determine surface temperature.USGS EROS Archive - Landsat - Atmospheric Auxiliary Data - NCEP/NCAR Reanalysis C2
The National Centers for Environmental Prediction (NCEP)/National Center for Atmospheric Research (NCAR) Reanalysis 1 products are annual Network Common Data Form (netCDF) files, which contain the daily values for each surface pressure, precipitable water, and air temperature. NCEP data are used in the surface reflectance algorithm for Landsat 4-7 data.USGS EROS Archive - Landsat - Atmospheric Auxiliary Data - GEOS-5 FP-IT C2
Data from Goddard Earth Observing System Model, Version 5, Forward Processing (GEOS-5 FP-IT) are used in the surface temperature algorithm for Landsat 7 data starting in 2000 as well as Landsat 8-9 data for Global products. The files are one file per 3-hour period containing one-time observation (8 files per day).USGS EROS Archive - Landsat - Atmospheric Auxiliary Data - ASTER GED C2
ASTER is an instrument on the Terra satellite. ASTER Global Emissivity Dataset (GED) is a global, 90-meter spatial resolution emissivity map of the Earth’s non-frozen land surfaces at different wavelengths in the thermal infrared spectrum. ASTER GED bands 13, 14, and Normalized Difference Vegetation Index (NDVI) are used in the surface temperature algorithm for Landsat 4-9 data.USGS EROS Archive - Landsat Archives - Landsat 8-9 OLI/TIRS Collection 2 Level-2 Science Products
