fldmean sea level pressure problem
Added by emily feng over 11 years ago
Hello,everyone,
I have a problem when I use command "cdo fldmean ipsl.nc opsl.nc" to calculate sea level pressure.
I use commands:
cdo yearmean psl_Amon_CCSM4_piControl_r1i1p1_000101-050012.nc yrmnpsl.nc
cdo fldmean yrmnpsl.nc pslm.nc
After fldmean command, psl of each year is the same. Does anyone have any ideas to solve this problem?
Thank you very much!
Best regards!
emily

Hi,
As far as I know, I don't think CDO is doing anything wrong.
If you really want to see the difference; may be it's a good idea to play with "anomaly" or something similar (I'm not an expert ... but, just a suggestion)
try;
cdo -sub psl_Amon_CCSM4_piControl_r1i1p1_000101-000512.nc -timmean psl_Amon_CCSM4_piControl_r1i1p1_000101-000512.nc anom_file.nc cdo -output -fldmean -yearmean anom_file.nc
Now you see the difference!
Cheers,
J.
