How to obtain the mean air temperature under specific height (in meters)?

Hi everyone.
Following the methodology provided by a paper, I am trying to calculate the temperature horizontal advection. According to this paper, to finish this, the mean air temperature under the regionally averaged PBLH should be calculated.
The regionally averaged PBLH can be easily calculated, but how should I obtain air temperature under this height (in meters)?
Is that possible to use interplevel in wrf-python?

Many postprocess packages such as NCL and Python provide the capability of vertical interpolation from model level to height/pressure level. Please see the examples at:
(1) NCL: NCL Graphics: WRF Interpolations and Cross Sections
(2) Python: How To Use — wrf-python 1.4.0 documentation

PBLH is an output variable included in wrfout. It is easy to calculate its regional average and find all grid points below the average PBLH. Then we can obtain average T over these points.

Thanks a lot. I have successfully calculated temperature advection at a certain timepoint.
But I have one more question: is there any solutions for calculating accumulated temperature advection during a time period?
For instance, I have wrfout at 15:00 and 16:00, now I can calculate temperature advection at these timepoints, but can I calculate temperature advection during the hour?
 
It is hard to obtain the time-average advection solely based on wrfout. This is because all variables in wrfout are instantaneous variables.
