[Wrf-users] How to crop the metgrid.exe result ?

[Eric Altshuler]

Hello,

I don't believe there is any variable "trim_value" in the WPS namelist. I think this variable is used in OBSGRID. Check the WRF-ARW Users Guide.

Hi,
You should define your model domain, your specific region, by
geogrid.exe (by setting "trim_value" in your WPS namelist)  before you
run metgrid.exe.

Hi,

After i metgrid.exe, the output file is 

met_em.d0N.YYYY-MM-DD_HH:mm:ss.nc

How can i crop the the specific geographic region of this file ? such as
if i just want to crop the result from China, while the metgrid.exe
outputted date about the global.

Is there have any netcdf editor can do such kind of work ?

Regards,
