USGS EROS Archive - Landsat - Atmospheric Auxiliary Data
Landsat Collection 2 Level-2 surface reflectance and surface temperature data processing requires atmospheric auxiliary data from multiple external sources. The required data is extracted from the source and the components specific to generating a Collection 2 Level-2 product are repackaged and are available to download.
USGS EROS Archive - Landsat - Atmospheric Auxiliary Data - TOMS C2
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.
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 - MODIS Fused C2
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 - 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 - LCMAP- Continuous Change Detection Classification v1.1 (CCDC) Products (U.S.)
The Land Change Monitoring, Assessment and Projection (LCMAP) project has generated an integrated suite of annual land cover and land surface change products for the United States based on time series data from the Landsat record from 1985–2019. LCMAP Collection v1.1 Science Products are based on the USGS implementation of the Continuous Change Detection and Classification (CCDC) algorithm.
