Step 1: Getting meteorological data from IFS or ERA5 reanalysis
...
Alternatively, users can download the freely available ERA5 global reanalysis data from the C3S Climate Data Store (CDS) to drive WRF meteorological component. Please read through How to download ERA5. You also need to have a look at the parameter table in ECMWF WRF Test Data for retrieving relevant data.
