[ncl-talk] 3D variable output

[Dennis Shea]

I hesitate to answer this question because it is not clear what is desired.

What version of NCL are you using?   Did you read the documentation for*
wrf_user_intrped *?
<http://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_intrp3d.shtml>
It states: This function is deprecated in NCL version 6.6.0. Use
*wrf_user_interp_level*
<http://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_interp_level.shtml>
for horizontal interpolations and *wrf_user_vert_cross*
<http://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_vert_cross.shtml>
for vertical cross sections.
----
I am not a WRF user and have never used the above functions.

   ua = wrf_user_getvar(a,"ua",time)
   p  = wrf_user_getvar(a,"pressure",time) ; total pressure

; Horizontally interpolate to pressure coordinates ("p")

   pres!0 = "pres"            ; create vertical coordinate variable
   pres at units = "hPa"
   pres&pres = pres

   UA_X = wrf_user_intrp3d(ua,p,"h",pres,0.,False)   ; pre 6.6.0
   UA_X!0 =  "Time"
   UA_X!1 = "pres"
   UA_X&pres = pres
   printVarSummary(UA_X)
   printMinMax(UA_X,0)
