Does anyone know what are we talking about in practice in terms of weather forecast prediction improvement? Like MAE/RMSE

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.

I am not sure what to make if your question.

Ultimately better data will lead to and enable better models and forecasts, but I'm sure it's not super easy to put a number to that.

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.

Somebody else must know more.

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.

There are even Hackathons from ESA:

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

Very cool!

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.

Europe is behind in launchers, but the stuff they send up is top-notch.

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

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
