The ERA5-Land dataset is available for public use for the period from 1981 to 2-3 months before the present. ERA5-Land provides hourly high resolution information of surface variables. The data is a replay of the land component of the ERA5 climate reanalysis with a finer spatial resolution: ~9km grid spacing. ERA5-Land includes information about uncertainties for all variables at reduced spatial and temporal resolutions.
The entire ERA5-Land dataset from 1950 to present is expected to be available for public release later in 2021.
The model used in the production of ERA5-Land is the tiled ECMWF Scheme for Surface Exchanges over Land incorporating land surface hydrology (H-TESSEL). See IFS model documentation CY45R1 for more details.
The first years of production highlight the adding value of the dataset to ERA5 surface fields and meet the needs of the users for a more accurate surface dataset.
Period from 1981 to 2-3 months before the present.
Spatial resolution ~9 km
Further ERA5-Land references and related information are available from the ECMWF e-Library.
