Some Python versions of All variables in wrfout are in model levels ( either full or half levels). int2p_n_Wrap is used to do the interpolation and maintain the appropriate meta data. 6 release of MetPy in September 2017, greatly simplifies vertical interpolation and coordinate interpolation by performing the necessary calculations within vectorized library code, allowing for simple and relatively fast usage within data visualization scripts. There are slightly different approaches that may be used. The data is available using a thredds server.

Following best practices when choosing a Dear WRF users and NCL guys, when I use wrf_user_intrp3d in NCL to make a vertical interpolation (in meter), I found the first interpolating level is always missing value. 9x1. The coefficients A k and B k are constants whose values effectively de-fine the vertical regrid_15. This is a bit out-of-date; we'll try to update it when we can. Note that a 0.
