[pyngl-talk] reading wrf output without lat lon variables

I have a problem with reading wrf output file (Projection is Polar Stereographic); i want to compare wrf model output with observations at specific latitude-longitude coordinates, but output netcdf file has no latitude and longitude variables.
I am using my python environment for reading this netcdf file, where PyNGL and PyNIO are already installed. As an example, temp variable in this output has attributes below:
short T2 [ Time|1, south_north|150, west_east|150 ]
FieldType : 104
MemoryOrder : XY
description : TEMP at 2 M
units : K
coordinates : XLONG XLAT XTIME
add_offset : 273.8086
scale_factor : -0.0005068767
Here, T2 variable has “Time", “south_north" and “west_east” dimensions and “south_north" and "west _east" dimensions have both 150 grids. There is no XLAT and XLONG variables in the netcdf output, so how can i get the temperatures at any lat-lon points with just grid numbers?
Thanks in advance,
