Useful for
- Use cases llm-inferred
- FRA antecedent soil moisture and catchment wetness context from long-term hourly land-surface records · Drainage strategy: soil moisture and temperature inputs for infiltration and SuDS assessment · Land-surface forcing for hydrological or flood/drought modelling where no local gauge or station record exists
- Audience llm-inferred
- flood consultants · hydrologists · drainage engineers · environmental consultants · climate risk analysts · GIS analysts
Limitations
- Constraints docs-verified
- Model estimates carry uncertainty that grows further back in time · Land fields are simulated, not directly observed; observations only influence them indirectly via atmospheric forcing · Native grid is ~9 km, so local-scale detail is limited despite the 0.1° distribution grid · Distributed in GRIB format only per the docs page; other formats need conversion
