As far as I can tell, they say: "Mission control and data distribution are managed by EUMETSAT." They have published their own blog post here: https://www.eumetsat.int/features/see-earths-atmosphere-neve...

There they say that: "Observations made by MTG-S1 will feed into data products that support national weather services …". So I guess there will be no simple, publicly available REST API or so... but if anybody finds anything, let us know here :)

As most EU projects yes. There was test data released last year to get you started.

Yes, it will be freely available to the public

I guess you will be able to access the data with copernicus (usually thy even provide raw L0 data)

This data is from the third generation of Meteosats, which are the European meteorological satellites. A lot like GOES in the north-America. The main improvement is really significant improvement in resolution. The resolution is, depending on the channel, 9 times better than in the second generation. The main improvement in forecasting comes due to better information in the initial condition of the numerical weather prediction, but it is hard to quantify in advance. I'd be surprised if MAE, over the 15 days the prediction spans, would improve more than 0.1 C, if we talk about the raw prediction. There are plenty of things that this data is used for, but I would say that improved nowcast of cloud coverage, and energy production related parameters are likely to benefit most from the improvement in resolution.

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.

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.

If you are ever in Munich and want to find out more, be sure to visit the ESO Supernova[0].

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 are even Hackathons from ESA:

"Act in Space"

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

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
