Screenshot

None yet. Requested from incident.archivist@ in addresses.json (capture: only if its terms allow: otherwise the link). 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

The reference global model: chart catalogue (mean sea level pressure and wind, ensemble meteograms for any point, extreme forecast index). A subset of IFS and AIFS output is open data.

Forms: maps, models, api.

What it does best

The ensemble meteogram: the spread of 50 runs for one place as box-and-whisker by time step, uncertainty made visible. The extreme forecast index shows how unusual the forecast is for that place.

What we take from it

Show a spread, not one line, for Lisbon's gusts where we have several models; say how unusual a value is for the place.

Data and models it says it uses

Its own models: IFS and AIFS (read on its open-data page).

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

API and feeds

open data files (GRIB) and a client; charts via Open Charts
