Modifying input data at a specific point

[Brian LuValle]

Hello,
I have been conducting experiments to determine the affects of altering certain local weather variables in small regions on larger weather patterns. Im using the GFS NCEP data package with WRF4.5, and I was wondering how I can view and modify wrf initial conditions within a specific geographic region?
Thank you,
Brian LuValle

Brian,

If you are familiar with Fortran, please download the utility read_wrf_nc from the website:

read_wrf_nc Options

Then follow the instruction to modify the data over the specific area you are concerned.

Some other software packages like NCL and Python etc. can also be used to modify netCDF data.
