Time series of JAS means ?

Hi,

I've got a time series of monthly average over about 2500 years (29000 time steps).

I want to produce a file with the series JAS means only. I cannot figure out a way to do it.

Any hint ?

Thanks

Olivier

use the selmon operator, for example,

cdo -sinfo -yearmean -selmon,7/9 in_file

will give the mean of JAS for all years (2500 time steps)

cdo -sinfo -ymonmean -selmon,7/9 in_file

will give the multiyear mean of individual J A S (3 time steps)

Cheers,
J

(1-1/1)
