Landsat 

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.

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).

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.

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).

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.

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.

Landsat 8-9 Operational Land Imager (OLI) and Thermal Infrared (TIRS) Collection 2 Level-2 Science Products 30-meter multispectral data.
