Hello everyone,
I am trying to determine which weather stations are used in the data assimilation process to produce the ERA5 reanalysis. I am studying an area with limited synoptic weather stations and am interested in understanding if there is any redundancy between the ERA5 reanalysis data and the weather station data.
Additionally, I am using the ERA5-Land reanalysis. From my understanding, the process for ERA5-Land is different, and there should be no redundancy in the information. Is this correct?
Thank you for your assistance.
Cheers
