mask out a region with CDO
Added by Victoria Naipal about 10 years ago
I have a netcdf file with a variable c(time,lat,lon), and I have another netcdf file with a masked region in it, it has a variable mask(lat,lon), which is 1 for the masked region in the file, all other values are no data.
Now I want to mask the same region out on my nc file with the variable c.
I tried cdo maskregion, but it didn't work.
How can I do this with cdo?

You can use the CDO operator div to divide all variables in the first input file by a variable/mask in the second inputfile:
cdo div ifile1.nc ifile2.nc ofile.ncAll variables needs to have the same horizontal grid size.
