Dear NCL users,

When I use "wrf_user_intrp3d" to vertically interpolate my wrfoutXXX.ncl from eta level data to pressure level data, I am curious that how NCL make this interpolation. Is it linearly interpolation or other kinds of interpolation? I looked through the function script in WRFUserARW.ncl about wrf_user_intrp3d, however, in the interpolation part, it use another two functions to make this interpolation: wrf_interp_2d_xy or wrf_interp_3d_z.

Is there anybody familiar with this interpolation? Please explain for me a little so that I can better understand how NCL works.

With Best regards,
