High resolution solar radiation HANNA data over the Alps. The average of the surface solar incoming radiation over the years 2019 to 20020 shows small scale variations due to clouds, snow cover, altitude and terrain shadow.
🌞 Just released: HANNA – high-res solar radiation data for Europe!
15-min resolution, \~1 km grid, derived from Meteosat rapid scans with terrain-aware processing.
Perfect for PV modeling, now available for 2019–2020
via CM SAF.

🇨🇭 Switzerland has launched a new national drought early warning system!
It combines satellite and model data − including surface temperature data from EUMETSAT’s CM SAF − to assess vegetation stress.
A great example of climate data in action:

Vintersesongen er over i Arktis og sjøisen vil smelte gjennom våren og sommeren 🧊
Sjøisen sin maksimale utbredelse ble 14,43 millioner km², 1 million km² mindre enn normalt.
– Det er det laveste nivået vi har målt etter vintersesongen, sier klimaforsker Thomas Lavergne.
