The satellites of the Copernicus Earth observation programme provide a wealth of data to climate scientists around the globe.
The identical Sentinel-3a and 3b satellites work in synchrony, monitoring the health of our land and oceans, helping scientists ‘take the pulse of the planet’ as our climate changes.
This interactive Sentinel-3 satellite was one of four I developed for the Learning Zone youth education portal, to explain what they do and how their data is used.
