Summary
ERA5-Land is a state-of-the-art global reanalysis dataset produced by ECMWF within the Copernicus Climate Change Service, providing enhanced 9 km resolution land surface variables over seven decades. The dataset integrates high-resolution land surface modelling with downscaled meteorological forcing and demonstrates improved representation of hydrological processes, particularly soil moisture and river discharge, though snow depth performance is geographically variable. As a foundational tool for land monitoring applications, ERA5-Land enables consistent, multi-decadal analysis of water and energy cycle trends and anomalies across terrestrial regions globally.
UK applicability
ERA5-Land offers UK-relevant soil moisture, precipitation, and hydrological data at 9 km resolution, supporting agricultural water management and drought/flood risk assessment. The dataset may enable monitoring of UK farming system responses to climate variability, though site-specific validation against UK in situ observations would strengthen applicability to local soil and land use studies.
Key measures
Soil moisture, lake surface representation, river discharge, snow depth, skin temperature, root mean square error, horizontal resolution (9 km), temporal resolution (hourly)
Outcomes reported
The paper presents ERA5-Land, a 9 km resolution global reanalysis dataset spanning 1950 to present, describing the evolution of water and energy cycles over land. Evaluation against independent observations and reference datasets demonstrated enhanced representation of soil moisture, lake description, and river discharge compared to predecessor datasets.
