Free, ad-free and built to teach
METEO / Atlas has no adverts and no subscriptions. It is an educational project: showing how a weather forecast is really made, with open data and without hiding the uncertainty. Using it is free; keeping it running is not.
Three ways to lend a hand
Buy us a coffee
A one-off or monthly contribution, whatever size you like. It pays for the server that downloads the models every 20 minutes and for the tools we build it with, artificial intelligence included.
Secure payment on Ko-fi: we never see or store your payment details.
Support it as an organisation
Companies, associations and other organisations can also chip in with a contribution. It doesn't unlock anything extra and there are no adverts: at most, a thank-you mention down below, if you'd like one.
Are you a local council or a civil protection service? See the report for your municipality's critical points.
Use it and tell us
Answer “Did we get it right?” after alerts, and tell us what is unclear and what you miss. Every piece of feedback improves the tool for everyone.
Have a website? Put your town's weather on it: it's free and helps us get known.
Why educational
Understanding the weather, not just checking it.
- Uncertainty in plain sight: “9 out of 10 scenarios” teaches more than a bare percentage.
- Accuracy, published: the dashboard itself shows how wrong each model gets it.
- Open data and credited sources: ECMWF, NOAA, DWD, Copernicus and AEMET, each with its licence.
- For classes and workshops: past episodes, model comparison and a notebook to study cases. If you teach or run workshops, get in touch.
