Added by Abdoulaye SY over 6 years ago

Hi
I want to concatanate daily .nc files (from 2001_01_01.nc to 2001_12_31.nc) which dimensions are lat and lon to yearly output file with time, lat and lon dimensions.

Thanks

Hi Abdoulaye,

if your daily files do not have a time dimension you can create it using settaxis operator.

cdo -f nc -settaxis,2001-01-01,,1day -cat '*.nc' outfile

Hello Karin
thank you for the answer
It works well

is it possible to create time dimension on the basis of the filename? I mean if I have a data file for one year but with some missing dates then will it create the time/date dimension correctly?

Without any further information I would say you have to write a shell script to do that.
