change season definition
Added by Merce Casas Prat over 8 years ago
Hello!
When using, for example, seasavg, by default seasons are defined as DJF, MAM, JJA, SON (if I'm not wrong). I was wondering how to change this criteria in order to define seasons as JFM, AMJ, JAS and OND, when using any cdo function to compute seasonal statistics.
Thanks
Merce

Yes, the first season is starting in December. You can change it to January with:
export CDO_SEASON_START=JAN
You can check it with the CDO option -v:
cdo -v seasavg ifile ofile

Hi Uwe,
I am also interested in changing the default seasons, but to DJF, MAM, JJAS and ON. How can I achieve this? Please also suggest how I can set the defaults back on after I am done with this particular application.
Thanks!
