What's in it

Data offered docs-verified: downscaled daily climate model output for SAI scenarios · pr · rsds · tas · tasmax · tasmin · dtr
Coverage docs-verified: Global
Resolution llm-inferred: 0.25° spatial, daily temporal
Formats docs-verified: NetCDF · Icechunk
Access docs-verified: Public, anonymous HTTPS/S3 access (us-west-2); output data CC BY 4.0; input data under multiple licences plus additional Terms of Data Access

Useful for

Use cases llm-inferred: Extract UK-domain pr and tas time series from the global 0.25° grid for climate-change context in flood risk assessments · Compare SAI scenarios (G6-1.5K, G6-1.5K-end) against SSP2-4.5 and historical runs for climate resilience options appraisal · Derive tasmax, tasmin and dtr inputs for heat-stress or thermal screening in drainage and civils design reports
Audience llm-inferred: climate risk consultants · hydrologists · drainage engineers · civils engineers · planners

Limitations

Constraints llm-inferred: Full dataset is ~21TB, so selective access to groups is needed · Only two GCMs (CESM2-WACCM6, UKESM1-1-LL) and two downscaling methods (BCSD, QDMSD) · Termination shock scenario is only available for CESM2-WACCM6 · Group layouts differ between the two GCM stores · Opening the full DataTree can take a couple of minutes · Input data carries multiple licences and additional Terms of Data Access · Not UK-specific; UK extraction must be done by the user · Requires Python tooling (icechunk, xarray, zarr-python)
