Help with using cdo to take mean on Ensebmle members grib
Added by Ran Glattstein over 5 years ago
Hi,
I have a Grib file that contains 20 meassages corresponding to 20 ensemble members of some Ensemble model forecast (say GEPS 20181221_12z) for some Geo focus (US).
I would eventually like to have a grib file with 1 meassage that will contain the same fields but its values will be the mean of the 20 original messages.
Can I do it with CDO?
I already manages to seperate the big GRIB file into 20 diffrenet files, but still I don't know how to take mean on these files.
Thanks in advance,
Ran.

Hi Ran,
use the timmean operator to compute the mean for all entries (messages) in you file.
cdo timmean geps_0p50_TMP2m_20181212_12_018.US.minigrib outfile-Karin
