Hi,

I know that ATM_P.mon is not nerCDF, but I was of the impression that cdo worked on other types of files.

I have tried using cdo to convert, but the program crashed, so I am considering that didnt work

I used the lats4d.gs script from here (ftp://grads.iges.org/grads/scripts/lats4d.gs), but I got this error.

ga-> lats4d -v -q -i 89.MScSim/ATM_P.mon.ctl -o first.nc
lats4d: this build of GrADS v2.0.a9 does not include the LATS option
lats4d: please try "gradsnc" or "gradshdf", version 1.7beta9 or later
lats4d: exiting from GrADS...
No hardcopy metafile open
GX package terminated

Hamza, do you use this same version of grads and installed some add on function or is there some other way?

Thank you for your help.

Regards,

James

if you have grads, after open it, you can use this command to convert netcdf and merge them,

lats4d -v -q -i 89.MScSim/ATM_P.mon.ctl -o first.nc
lats4d -v -q -i 90.MScSim/ATM_P.mon.ctl -o second.nc
cdo mergetime first.nc second.nc result.nc

There is a cdo command also, however it doesn't work with some of the Regcm outputs because of pdef definition,

you can try it also
cdo -f nc import_binary 89.MScSim/ATM_P.mon.ctl first.nc
cdo -f nc import_binary 90.MScSim/ATM_P.mon.ctl second.nc

Best Wishes
