Utility: read_wrf_nc

• This utility was created to allow a user to look at a WRF netCDF file at a glance
• What is the difference between this utility and the netCDF utility ncdump?
  • This utility has a large number of options, to allow a user to look at the specific part of the netCDF file in question
  • The utility is written in Fortran 90, which will allow users to add options
• Can be used for both WRF-ARW and WRF-NMM cores
• Can be used for geogrid, metgrid and wrf input/output files
• Only 3 basic diagnostics are available: pressure, height, and tk. These can be activated with the -diag option (these are only available for wrfout files)
  

Obtain the utility from the WRF Download page (you must be a registered user to download any code - it is free)
 

Compile

The code should run on any machine with a netCDF library.

To compile the code, use the compile flags at the top of the utility.
e.g., for a LINUX  machine you need to type:

pgf90  read_wrf_nc.f  -L/usr/local/netcdf/lib  -lnetcdf  -lm 
         -I/usr/local/netcdf/include -Mfree  -o read_wrf_nc

If successful, this will create the executable: read_wrf_nc

 

Run

./read_wrf_nc wrf_data_file_name [-options]

options:    [-h / help] [-att] [-m] [-M z] [-s] [-S x y z]
                [-times] [-t t1 [t2]] [-v VAR] [-V VAR] [-w VAR]
                [-ts xy X Y VAR VAR .....] [-ts ll lat lon VAR VAR .....]
                [-lev z] [-rot] [-diag]
                [-EditData VAR]
