Note that ERA5-Land was forced by the ERA5 Preliminary back extension, rather than by the final ERA5 back extension for data older than 1979. ERA5-Land uses forcing fields based on the final release of ERA5 (i.e., expver=0001) for data after 1978. ERA5-Land comes with a series of improvements making it more accurate for all types of land applications. In particular, ERA5-Land runs at enhanced resolution (9 km versus 31 km in ERA5). The temporal frequency of the output is hourly and the fields are masked for all oceans, making them lighter to handle. ERA5-Land is produced under a single simulation, without coupling to the atmospheric module of the ECMWF's Integrated Forecasting System (IFS) or to the ocean wave model of the IFS. It runs without data assimilation, making it computationally affordable for relatively quick updates. For example, if significant improvements of the land surface model are implemented, the whole or part of the dataset can be reprocessed in a relatively short period. Also, updates are possible in case improved auxiliary datasets are used as input for the production. Observations indirectly influence the simulation through the atmospheric forcing of ERA5. This forcing drives the ERA5-Land single simulation and it has been obtained by assimilating observations through a 4D-VAR data assimilation system and a Simplified Extended Kalman Filter. The core of ERA5-Land is the Tiled ECMWF Scheme for Surface Exchanges over Land incorporating land surface hydrology (H-TESSEL). It uses version CY45R1 of the IFS. onGoing datahelp@ucar.edu pointOfContact monthly dataset https://gdex.ucar.edu/images/ds_logos/default_200_200.png Logo thumbnail from URL png NetCDF4 dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral ECMWF ERA5 > ECMWF ERA5 Atmospheric Reanalysis U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-03-19 revision 23.6 NASA Global Change Master Directory orginator Valids List: Platforms ERA5 > ECWMF ERA5 Reanalysis U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-03-19 revision 23.6 NASA Global Change Master Directory orginator Valids List: Projects EARTH SCIENCE > AGRICULTURE > SOILS > SOIL CLASSIFICATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC PRESSURE > SURFACE PRESSURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > LONGWAVE RADIATION > DOWNWELLING LONGWAVE RADIATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC RADIATION > SHORTWAVE RADIATION > DOWNWELLING SHORTWAVE RADIATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > AIR TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC TEMPERATURE > SURFACE TEMPERATURE > DEW POINT TEMPERATURE EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WATER VAPOR > WATER VAPOR PROCESSES > EVAPORATION EARTH SCIENCE > ATMOSPHERE > ATMOSPHERIC WINDS > SURFACE WINDS > U/V WIND COMPONENTS EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > PRECIPITATION AMOUNT > HOURLY PRECIPITATION AMOUNT EARTH SCIENCE > ATMOSPHERE > PRECIPITATION > SNOW WATER EQUIVALENT EARTH SCIENCE > BIOSPHERE > VEGETATION > VEGETATION COVER EARTH SCIENCE > BIOSPHERE > VEGETATION > VEGETATION SPECIES EARTH SCIENCE > CRYOSPHERE > SNOW/ICE > ICE EXTENT EARTH SCIENCE > LAND SURFACE > LAND USE/LAND COVER > LAND/OCEAN/ICE MASK EARTH SCIENCE > LAND SURFACE > SURFACE THERMAL PROPERTIES > HEAT FLUX > LATENT HEAT FLUX EARTH SCIENCE > LAND SURFACE > SURFACE THERMAL PROPERTIES > HEAT FLUX > SENSIBLE HEAT FLUX EARTH SCIENCE > LAND SURFACE > TOPOGRAPHY > TERRAIN ELEVATION EARTH SCIENCE > TERRESTRIAL HYDROSPHERE > GLACIERS/ICE SHEETS > GLACIERS EARTH SCIENCE > TERRESTRIAL HYDROSPHERE > SURFACE WATER > SURFACE WATER FEATURES > LAKES/RESERVOIRS EARTH SCIENCE > TERRESTRIAL HYDROSPHERE > SURFACE WATER > SURFACE WATER PROCESSES/MEASUREMENTS > WATER DEPTH U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-03-19 revision 23.6 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None grid 0.1 eng utf-8 climatologyMeteorologyAtmosphere -180.0 180.0 -90.0 90.0 2019-03-01T0100+00 2026-03-01T0000+00 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 3791199.215 https://gdex.ucar.edu/datasets/d633008/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d633008/dataaccess/ https Data Access Related Link download none asNeeded
