How hot the land surface gets, hourly (Americas, 4 km)
What it measures. How hot the land surface gets, reported hourly for every pixel across North and South America, along with an estimate of how uncertain each temperature is.
How it's made. Calculated from the GOES series of geostationary weather satellites (GOES-8 and 10 through 17) using a temperature-and-emissivity algorithm, covering 2000 through 2023 at 4-km resolution.
How & where you'd use it. Lets researchers watch how land heats and cools through the day and across seasons, useful for studying heat, drought, agriculture, and urban climate.

Official description
The NASA Making Earth System Data Records for Use in Research Environments ([MEaSUREs](https://www.earthdata.nasa.gov/about/competitive-programs/measures)) GEOLST4KHR version 2 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 17 satellites for the years 2000 through 2023. 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.
