Hourly ground-surface temperature worldwide (Copernicus)

CLMS LST Global 3km hourly V3
land ESA ESA Copernicus active COGNetCDF
In plain English

What it measures. Gives the temperature of the land surface itself (not the air above it) every hour of the day, for pixels across the globe.

How it's made. Produced by ESA Copernicus from geostationary weather-satellite thermal observations at roughly 3-kilometer resolution, from January 2018 to the present.

How & where you'd use it. Feeds weather and climate models, urban heat studies, fire-risk and drought monitoring, and any work needing frequent updates on how hot the ground gets.
