Averaging along a longitude/latitude

Added by Lyndon Mark Olaguera about 2 months ago

Dear CDO experts,

I am getting the following error:

cdo(1) sellonlatbox (Abort): Longitudinal dimension is too small!
terminate called recursively
terminate called without an active exception
ndjf.sh: line 10: 714240 Aborted                 (core dumped) cdo fldmean -sellonlatbox,128,128,5,20 -sellevel,92500 uwnd_ndjfm_1979-2020.nc cold_surge_ndjfm_1979-2020.nc

I just want to get the average between 5-20 degrees North along 128E. How can I do this in CDO?

Thanks!

Hi Lyndon,

take a look to this post. It is very a similar problem.

Kind regards,

The value lon max must be greater than lon min. So try to find a minimal value range that includes the 128°.

Try something like

cdo -sellonlatbox,127.5,128.5,5.,20. infile outfile
    (1-2/2)
