[ncl-talk] NCL function wrf_user_getvar

[Israt Jahan]

Dear NCL users,
I have a question about the NCL function "wrf_user_getvar". I see this
function can extract data from  WRF files and calculate the requested
diagnostic. One of the available diagnostics is "z/height" which is labeled
as the "full model height in m" in this site wrf_user_getvar (ucar.edu)
<https://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_getvar.shtml>.
>From WRF output files, I need to find temperature at 1000 m above ground
level. I am doing the following:
1. ht=wrf_user_getvar(NCDF_File,"z",0) where NCDF_File is a list of WRF
netCDF files
2. tk=wrf_user_getvar(NCDF_File,"tk",0)  to get temperature in K
2. temp_1km=wrf_user_interp_level(tk,ht,1000,0) to get temperature at 1 km

My question is: is the diagnostic "z/height" that we get from
"wrf_user_getvar" measured from ground level or sea level?
If it is measured from sea level, what should I do to get z from ground
level?

Thank you so much.
Best,
Israt
