ERA5-Land daily averaged data

This is a subset of ERA5 data for world land surface quantities called ERA5-Land daily data from 1950 to present. The data are available from 1950 until the last closed month and updated monthly and are regridded to a regular lat-lon grid of 0.1 degrees.

They are presented as a Zarr archive optimised for both spatial and time analysis.

This dataset is produced by the Earth Data Hub Team based on the ERA5-Land hourly data dataset and uses the standard UTC day as a base for averages and accumulations. That is, the day starts at 00:00 UTC and ends at 23:59 UTC on all pixels irrespective of the latitude and the local time. Note that for accumulated variables, like the total precipitation tp, the original ECMWF data resets the values at the start of the UTC day on all latitudes already.

For instantaneous variables, e.g. the 2 meter temperature t2m, the operation applied is the Xarray .resample("D").mean() method. For accumulated variables the values are the total accumulation for the day.
