cdo ensmean (Warning): Inconsistent ensemble file, too few time steps (cdo 1.9.3)

Added by Lyndon Mark Olaguera about 6 years ago

Hi all,

I encountered this warning message while taking the ensemble of years with 365 and 366 days.

Here are the details of CDO that I am using:

Hi Lyndon,

the warning is telling you exactly what happened. You can compute the ensemble mean only over the same days, if one is missing it can't be computed. The documentation said:

All input files need to have the same structure with the same variables.

So time must also be the same.

Hi Karin,

Many thanks for the response.

I used the ydaymean instead after merging the files.
