ECMWF Reanalysis v5
ERA5 is the fifth generation ECMWF atmospheric reanalysis of the global climate covering the period from January 1940 to present. ERA5 is produced by the Copernicus Climate Change Service (C3S) at ECMWF.
ERA5 provides hourly estimates of a large number of atmospheric, land and oceanic climate variables. The data cover the Earth on a 31km grid and resolve the atmosphere using 137 levels from the surface up to a height of 80km. ERA5 includes information about uncertainties for all variables at reduced spatial and temporal resolutions.
ECMWF Reanalysis v5 - Land
ERA5-Land is a reanalysis dataset providing a hourly high resolution information of surface variables over several decades at ~9km grid spacing and covering the period from 1950 to 5 days before the present.
ERA5-Land, developed by C3S at ECMWF, has been produced by replaying the land component of the ECMWF ERA5 climate reanalysis. Monthly aggregates of the hourly fields are available.
