Ensmean missing value
Added by Anna marra about 9 years ago
Hi,
I am using ensmean to calculate mean precipitation from two different datasets. For one of them rain rate missing value is -9.99 and for the other one is -9.999. When I use ensmean unfortunately one of this value is not recognized as missing and it is used in the calculation of mean, giving obviously wrong results (negative precipitation). How can I set properly the missing value?
Thank you in advance.

Hi Anna!
Try the operator setmissval, like this:
cdo setmissval,new_undef if.nc of.nc
Where new_undef it's the new undef value.
Cheers,
Guilherme.

Try apply the operator in all files before of the ensemble. This way, all file will have the same undef value.

The CDO operator ensmean expects that all files have the same structure and the same missing value for the same variables. I have changed this for the next CDO release. A prerelease will be available tomorrow.
