Hi Hamza,
I have tried it with this code and it still didn't work
ga-> lats4d -v -q -i 89.MScSim/ATM_P.mon.ctl -o first.nc
Invalid QUERY argument: udc
WARNING: this build of GrADS v2.0.a9 does not include the LATS option
WARNING: "-format grib" or "-format coads" are not supported.
<RC> 1 </RC>
</IPC>
ERROR: cannot proceed without LATS; try specifying a different -format
lats4d: exiting from GrADS...
No hardcopy metafile open
GX package terminated
I will try installing another version of grads. Maybe that will work
I am using grads-2.0.a8.oga.1 and this command works with it,I am sending script as an attachment.Most probably, it will work with this version of grads.
As I understood, you want to use p coordinates. if p coordinates are not necessary for you, you can use rcm2netcdf tool of RegCM
Best Wishes
