 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 ?
It states: This function is deprecated in NCL version6.6.0.Use wrf_user_interp_level forhorizontal interpolations andwrf_user_vert_cross for verticalcross 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)

Dear NCL community,
The attached file is an NCL script, which is used to generate 3D u-wind based on WRF output.  However, the u-wind at different pressure level has different name as U500, U850 etc, and the "Level" always shows "0". Can one modify the script so that the u-wind variables has the same name "U", but with "Level" info to show the pressure level?
Thank you very much in advance!!!
Best regards,Mark_______________________________________________
