The MERRA-2 dataset is produced by the Global Modeling and Assimilation Office (GMAO) and the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC).


The ERA5 dataset is generated using Copernicus Climate Change Service Information. Copernicus Climate Change Service (C3S) (2017): ERA5: Fifth generation of ECMWF atmospheric reanalyses of the global climate. Copernicus Climate Change Service Climate Data Store (CDS), data access:!/home.

The data from April 2022 onwards will be the ERA5T on the reduced gaussian N320 grid. Before this, the ERA5T data on the reduced gaussian grid was not available.

Neither the European Commission nor ECMWF is responsible for any use that may be made of the Copernicus Information or Data it contains.
