Calibrated global sea surface temperature (Copernicus)

Sentinel-3 SLSTR Water Surface Temperature (NTC)
atmosphere ESA ESA Copernicus active
In plain English

What it measures. The temperature of the sea surface across the world's oceans, on a grid of about 1 km.

How it's made. Generated from the SLSTR thermal imager on ESA Copernicus' Sentinel-3 satellites as a Level-2 product, in a fully quality-checked version delivered after the fast near-real-time one.

How & where you'd use it. Underpins climate records, ocean-heat studies, and reliable inputs for long-term marine and weather research.
