Hello,
I am using ERA5 land data and to mask out sea points I am using landseamask netcdf file. But the longitude values/range in ERA5 land file and landseamask file is different. The CRS ( coordinate reference system ) is not described for both. Does anyone have any idea if they have same CRS or not ?
I also recently re-downloaded ERA5-land hourly data 1950-2023- I tried applying the same land-sea mask I was using on data I downloaded last year, and the mask must be regridded to apply to the data I downloaded over the last several months.
I also noticed all of my nc files I regridded to match the ERA5-Land data I downloaded a year ago don’t match the new ERA5-Land grid from the data I just downloaded. What changed in the ERA5-Land grid?
