convert all netcdf values > 0 to 1
Added by paolo de luca almost 4 years ago
Dear all,
I would like to apply the ERA5 land-sea mask (here attached) to some of my datasets. The mask has NaN set on the oceans, however it has some 0 < values < 1 over the coasts and lakes.
Since I am applying the mask using the function cdo mul I think that all the land values have to be = 1. Am I correct?
If this is the case, how can I convert all the land values (included coasts and lakes) to 1 with CDO?
Thanks for any help,
paolo

Hi Pao,
you can do that with the gec operator
cdo -gec,0 ERA5_land_sea_mask.nc ERA5_land_sea_mask_all_ones.nc
