I don't know what you mean. Data from the Copernicus program has always been fully available, served with a nice web UI, API for both near real time data and archives. It's the best source of open satellite data by far. As for the licensing, I never actually looked it up, so maybe you're right.

There are two aspects to this. The licensing commonly restricts you to small hobbyist use cases. There are typically restrictions on use of data, the amount of data, and retention of data. I've never looked at Copernicus data before but it appears to have the same kinds of restrictions. This is the licensing equivalent of "source available" rather than true "open source". Hopefully they are improving on this front. W…

Well it makes sense the public API has restrictions. They probably have separate enterprise licensing.

Unlikely. EU countries are consistently restrictive about access to this kind of data. Even when it is available, it often has odd restrictive licensing. This is an area where the US, with its liberal data access policies, is far ahead of Europe. Something else to keep in mind is that the data products are extremely large. It would be expensive to give the public access. I used to host these types of data sets for EU…

> restrictive about access to this kind of data

After all, we don't know if the weather consented to having its data displayed, or if it even allowed cookies.

Europe Is back on the map. It´s going slow but steady. Hope they involve community in their tech projects.

Europe has always been #1 in weather forecast.

Google partnered with European Center for Medium-Range Weather Forecasts (ECMWF) to build weather models. Which begs the question: why didn't it partner with NOAA on its home turf?

Europe is widely acknowledged as having arguably the best global weather systems. This isn't new. There are only a handful of organizations world-wide maintaining global weather models. The US government, uniquely, maintains two independent global weather models. Neither is as good as the European model. Arguments have been made for combining the US budgets to produce a best-in-class weather model but politics makes…

Which EU weather forecast provider is best and most accurate? I want to move away from just googling the weather or the weather app on my phone.

nice find. so you need a client_id to access the API

Read the data store user guide. You have to register.

For the datasets, I tried to access (like the full disc image in visible wavelength, MTG 0 degree), it is sufficient to register at eumetsat to get a username and password. The eumdac python tool is probably the easiest way to access the data:

https://pypi.org/project/eumdac/

(If you do not want to use python, the --debug option is quite useful to see exactly the request made. The output is either some JSON metadata or a large zip with the netcdf data)

EUMETSAT publishes data as CC-BY 4.0 past a timeliness of 1 hour https://www.eumetsat.int/data-policy/eumetsat-data-policy.pd...

Look for your dataset here https://data.eumetsat.int/ (Note: you need registration but it is free).

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 fin…

Most weather data isn't generally available by easy to query REST API's (at least not at the original sources). One side project I had I wanted to use NOMADs data, and it was quite a grind downloading and processing the raw datasets into something usable at an application level (or viable to expose via an API).

That’s why you have service/products that have the sole purpose of taking all these region specific data sources and processing them in to a generic json api.

The government orgs probably do it intentionally so they don’t have ten million devices pinging their servers to update weather widgets.

Probably because that was Deepmind, which has been located in Europe since before and after the google acquisition.

I find HRRR3 typically predicts better for my use cases, do you have more information on how Europe has always been #1 in weather forecast? I wonder about what the asian people have done too
