Re: Need help with wrf_user_intrp3d

Sangeeta,

If you read the documentation for wrf_user_intrp3d:

http://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_intrp3d.shtml

the "Description" section says:

   This function interpolates data from model levels to either a horizonal or vertical plane.

This basically means that your 3D array will be interpolated to a 2D array, which is exactly what is happening in your case.

Perhaps you need to create a 3D array yourself with the "new" statement, and then call wrf_user_intrp3d in a loop across your three heights.

I've CC'ed wrfhelp. Please correspond with them if you have further questions on your script.
