These data will be crucial for detecting fast-developing convective weather by revealing sudden shifts in instability, moisture, or wind – even before clouds begin to form."by perihelions - 17 hours ago
In other words, it is

Is there a more technical article describing this hyperspectral instrument somewhere? It sounds pretty novel.
edit: Also, I'm now confused about the ESA's claim to be "the first", because

- Only tangentially related: I have nothing but respect for EUMETSAT and their public data store. For past work projects I've had to interface with a pretty broad sample of the world's space and/or meteorological agency's public data stores and APIs and EUMDAC (EUMETSAT's API client) was top tier. Well documented, modern, fast, and generally headache free.by themisto - 16 hours ago
In fact, I have nothing but respect for any agency that makes free and public access to earth observation data a priority, regardless of how janky their API is.

I was confused for a minute on how it's both _geostationary_ and _over Europe_ -- you can't be geostationary if your orbit is not over the equator!
Turns out[1] the MTG-S1 satellite is in fact geostationary and parked at exactly 0°00'00"N 0°00'00"E (off the coast of Ghana), 42164 km up from the center of Earth, it's just pointing at Europe at an angle.
