CDO

Hello,

while analyzing atmospheric and oceanic fields during ENSO+ phases I stumbled over an issue with cdo enlarge.

Is the cdo enlarge command only mend to do horizontal enlargement of the grid?

When I tried to enlarge a 1D time series to a full 3D field (oceanic, 15 depth levels) to mask the 3D-field itself later on, cdo enlarge did not manage to produce a 3D field.
The commands I used were:

cdo sub -timmean -ifthen \
-enlarge,oceanic_3D.nc \
-setrtomiss,-10,0.5 -fldmean -runmean,5 -sellonlatbox,-170,-120,-5,5 -ymonsub oceanic_2D_tos.nc \
-ymonavg oceanic_2D_tos.nc \
-runmean,5 oceanic_3D.nc \
-timmean oceanic_3D.nc \
ENSO+_timmean.nc

I managed to create a mask by copying and merging the 2D mask a couple of times and use cdo setzaxis to set the oceanic_3D vertical axis, but this seems to be rather ugly.

Thanks,
Klaus
