PGW for ERA5
This is the first release of PGW for ERA5.
It does not yet have a special treatment for SST and sea ice changes but instead modifies surface temperature globally using the T_2m climate delta. This will be implemented within the course of 2022. For regions without sea ice, delta SST is very similar to delta T_2m and thus this missing feature is only relevant for high latitude PGW simulations.
