ERA5-Land post-processed daily statistics from 1950 to present

ERA5-Land is a reanalysis dataset providing a consistent view of the evolution of land variables over several decades at an enhanced resolution compared to ERA5. ERA5-Land has been produced by replaying the land component of the ECMWF ERA5 climate reanalysis. Reanalysis combines model data with observations from across the world into a globally complete and consistent dataset using the laws of physics. Reanalysis produces data that goes several decades back in time, providing an accurate descrip

Useful for

Use cases llm-inferred: Antecedent soil moisture context (volumetric soil water layers 1-4) for flood risk assessment and drainage design · Daily 2m temperature and 10m wind inputs for evaporation or ground-condition assessment on UK sites · Snow depth and snow cover history for winter ground and hydrology context in site investigations
Audience llm-inferred: hydrologists · flood consultants · drainage engineers · geotechnical engineers · environmental consultants

Limitations

Constraints docs-verified: Accumulated variables (e.g. total precipitation, runoff) are omitted, so they are not available from this entry · Daily statistics are computed during retrieval and are not part of a permanently archived dataset · Daily data is available with a 6-day delay · Native grid is 9 km, so local detail is limited · Only one version of the post-processed product is currently available
