Screenshot

None yet. Requested from incident.archivist@ in addresses.json (capture: yes). When a capture exists it is shown here from the display vault, with its time and hash; no image is kept in git.

What it shows, and how

A free JSON API over the open models of the national services (ECMWF, DWD ICON, Météo-France AROME/ARPEGE, and others), hourly, any point, with gusts; an ensemble API and a historical API. A call for Lisbon (hourly gusts and precipitation, two days) answered in 534 bytes.

Forms: api, models, timeline-hourly.

What it does best

Several models for one place in one call, with a clear licence.

What we take from it

The source for a model-spread strip for Lisbon (labelled analysis material, never a warning).

Data and models it says it uses

Open data of national services, listed on its licence page: DWD (ICON), ECMWF (IFS, AIFS), Météo-France, NOAA and others, each under its own open licence (read).

Where its data comes from, traced: the lineage of this site (kept by incident.meteorology@).

API and feeds

HTTP GET, no key, no sign-up
