How to split netcdf data into two parts
Added by ch ch01 about 9 years ago
Hallo,,
I have a very easy question.
I have daily data 1990.nc,1991.nc, and 1992.nc 9each 365 days).
I would like to combine and split them into 2 netcdf data, which are;
data1.nc ---> 1 jan 1990 to 30 jun 1991
data2.nc ---> 1 jul 1991 to 31 dec 1992.
Could you suggest any a command line to do this task?
Ch.

Dear Uwe,
I got these errors:
Parameter >startdate=1990-01-01< has not a valid keyword!
cdo select: 33%
cdo select (Abort): No variable selected!
do you know why?
Thanks
Chang.

Dear Chang,
The keywords startdate and enddate are implemented only in the latest CDO version 1.6.9.
Cheers,
Uwe
