What's in it

Data offered docs-verified: NOAA GFS weather analysis (variable subset) · 1-hourly analysis steps
Coverage docs-verified: Global · 2021-05-01 UTC to Present
Resolution docs-verified: 0.25° spatial; 1-hourly temporal step
Formats docs-verified: Zarr
Access llm-inferred: Public; anonymous HTTPS/S3 access via data.source.coop; licence see product README (not stated in docs)

Useful for

Use cases llm-inferred: Historical wind and pressure context for flood or storm event reviews over a UK catchment · Meteorological boundary inputs for drainage or hydrological model sensitivity tests on past periods · Bulk extraction of GFS analysis variables for climate baseline comparisons in environmental assessments
Audience llm-inferred: hydrologists · drainage engineers · flood consultants · GIS analysts · climate data scientists

Limitations

Constraints llm-inferred: Only a variable subset of GFS is provided, not the full model output · 0.25° global grid is coarse for small UK catchments and urban drainage · Requires Zarr-capable tooling to read · Licence not stated in entry; check the product README · Global US-origin dataset; UK extracts need clipping and reprojection
