I was curious but it’s surprisingly hard to find info. These guys [1] are pretty stoked about “nowcasting”—which seems to be on sub-10-minute timescales to issue local severe weather warnings and such. It appears current sounders don’t scan as often.
This project ppt from 2011 [2] references different requirements for different areas/teams and shows the instrument spits out readings at 150 Mbit/s, which seems like a good clip. Overall it sounds like a lot of local knowledge is involved in turning this output into forecasts. Maybe there’s not a precise answer to your question.
This is an improvement as it provides better data and has nothing to do with the models that are used in a separate step to forcast anything. But that is said in the article as well, with the satellite being the first hyperspectral view on Europe and North Africa.
Been pulling in some of the newer data and concepts from open-meteo to my home weather display specifically the ensemble data, helps to provide some level of spread over the forecast, I mean I am not that sure how useful it is but I kinda got used to reading it of the display.
I recently met a European space startup founder and was surprised to learn how much space innovation is happening in Europe with ESA. Europe wants to become less depended on SpaceX and NASA, and is heavily investing there. More funding + strong aerospace programs at universities like TU Munich has led to companies like ISAR Aerospace (SpaceX competitor), which is great to see.
I work in the domain, and it is true that many of the startups will almost entirely use free data, like from the sentinel satellites via ESA. It really lowers the barriers to entry, if you have a nice idea.
maiaspace (https://www.maia-space.com/) also intends to compete with SpaceX and is an Ariane spin-off, they're meant to do their first launch this year and start putting satellites in LEO in 27
There is also a Spanish company which according to them, they were the first private European company to reach space with their rocket: https://www.pldspace.com/en/
Small odd thing, but that's the first tracking warning modal I've seen that says they don't actually use tracking. And I can decline the no tracking? Kinda funny.

Somebody else must know more.

I am not sure what to make if your question.

I worked at one of the hosts of one these events years ago - very intersting people there!

Euclid, the latest ESA telescope is particularly mind-blowing, capturing a third of the visible sky in incredible detail.
Check out this update video, it's insane how they can zoom in on stuff: https://youtube.com/watch?v=rXCBFlIpvfQ
