Geostationary Earth Orbit Land Surface Temperature Hourly North and South America 4 km

PI: Kerry Cawse-Nicholson

The GEOLST4KHR Version 1 data product was decommissioned on December 15, 2022. Users are encouraged to use the GEOLST4KHR Version 2 data product.


The NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) GEOLST4KHR swath product provides per-pixel Land Surface Temperature (LST) with a spatial resolution of 4,000 meters (m). The product is produced daily in hourly increments using data acquired from Geostationary Operational Environmental Satellite (GOES) 8 and 10 through 15 satellites for the years 2000–2016. The GEOLST4KHR product provides LST values for both North and South America. The GEOLST4KHR data product utilizes the Modern-Era Retrospective analysis for Research and Applications Version 2 / Radiative Transfer for TIROS Operational Vertical Sounder (MERRA-2/RTTOV) Single-Channel Emissivity-Combined ASTER and MODIS Emissivity over Land (CAMEL) algorithm.

The GEOLST4KHR product provides layers for cloud mask, latitude, longitude, land surface temperature, and land surface temperature error. A low-resolution browse is also available showing land surface temperature as an RGB (red, green, blue) image in JPEG format.
