What's in it

Data offered docs-verified: ensemble weather forecasts (ECMWF AIFS ENS model) · variable subset (variables not listed in docs)
Coverage docs-verified: Global
Resolution docs-verified: 0.25°
Update frequency docs-verified: every 6h
Formats docs-verified: Zarr
Access docs-verified: Public; anonymous HTTPS/S3 access per ENTRY auth field; no API key stated; licence not stated in docs (see product README)

Useful for

Use cases llm-inferred: Short-range (0-15 day) ensemble rainfall and wind inputs for site works and construction programme weather-risk checks · Ensemble spread as a weather-scenario input for drainage or flood-risk sensitivity runs at catchment scale · Regional-scale weather context for climate-risk screening in planning or environmental assessments
Audience llm-inferred: hydrologists · drainage engineers · civils and construction planners · climate risk analysts

Limitations

Constraints llm-inferred: Only a variable subset is provided; the included variables are not listed in the docs · Forecast horizon is 0-360h (0-15 days) only; no historical record is described · Global 0.25° grid, so not suited to local-scale site analysis without downscaling · Licence not stated in docs; check the product README before commercial use · Product labelled _internal v0.1.0 and created 2 Jun 2026; version stability and maintenance status unclear (last updated 24 Jul 2026)
