Verticul sum of a subset of levels to replace one of the levels
Added by Noam Chomsky about 5 years ago
I have a netcdf with 10 levels. I would like to sun it's a set of those levels say level 2, 3, and 8 and store the result of the vertical some on level 2, so effectively overwriting level 2.
so far I have used this:
myexpr is
sellevel(myvar,2)+sellevel(myvar,3)+sellevel(myvar,8)
cdo exprf,myexpr file1.nc levelsum.nc
Than imagine I have to delete levels two, three, and eight from the original file and then combine with levelsum.nc.
But how do I replace level 2 with the result in levelsum.nc?

Is there a way to do this in one sweep? It seems that nco allows to overwrite specific levels with the result of algebra operations.

hi Noam!
I don't think it's directly possible with the -expr operator. NCO's ncap might be able to do it.
