Helio,
This is probably a CDO problem, but unfortunately there does not
seem to be a CDO users' list at this time. You might want to ask
the CDO authors at MPI about that.

My guess is that CDO has made an assumption about the data type of a
named attribute that is not true for your landsea*.nc files. If
there are more error messages than the single line that you showed,
then they may be the easiest way to diagnose the exact problem.
If not, then you might try ncdump -h landsea.nc, then look carefully
for a character attribute that CDO might expect to be a numeric
attribute. Unfortunately this involves some educated guessing about
what a Netcdf file should look like. The documentation for the
conventions indicated in the "Conventions" file attribute might help.
If you find a likely suspect, you can change the character attribute
to type double. This is a hacker's approach, but that is what I
sometimes do when confronted by mysterious errors from mysterious
software.
If you wish, you could post a sample ncdump -h here, and see if
anyone else might have an idea. HTH.

Hello,
Maybe it's an easy question but as I'm sort of new in the use of those
netcdf operators, here it goes:
I have a netcdf file which I can work without any problems with ncdump,
ncks, ncview, etc...but when I try to use cdo, cdo gtc, 0.5 landsea.nc
<http://landsea.nc> landsea01.nc <http://landsea01.nc>, for instance,
the returned message is:
"Error (cdf_get_att_double) : Attempt to convert between text & numbers"
Any idea of what's going on? Any kind of hint or suggestion is appreciated.
Thanks.
Cheers,
Helio
