Refined surface temperature and radiance imagery (Copernicus)

Sentinel-3 SLSTR Radiance and Brightness Temperature (NTC)
land ESA ESA Copernicus active
In plain English

What it measures. The carefully calibrated version of global brightness temperatures and radiances, at roughly 500-meter detail for reflective bands and 1-km for thermal bands.

How it's made. Made by ESA Copernicus from the Sentinel-3 Sea and Land Surface Temperature Radiometer as non-time-critical Level-1 products.

How & where you'd use it. Well suited to long-term climate monitoring and research on land and ocean surface temperatures.

Official description

The Copernicus Sentinel-3 SLSTR RBT products provide global brightness temperatures and radiances with a spatial resolution of 500 meters for reflectance bands and 1 kilometer for thermal infrared bands, useful for environmental monitoring and climate studies.
