!-----------------------------------------------------------------------
! To recover the missing heights for the MULTI-LEVEL (KXS>1) OBS data
!
! (1) To compute the heights based on pressure(P), and available
! temperature(T) and specific humidity(Q) under the hydrostatic
! assumption.
!
! Using the available observed heights to calibrate the computed
! heights, then these calibrated and computed heights are used
! where the observed heights are missing.
!
! (2) When the hydrostatic assumption can not be applied at the bottom
! (K_START > 1) or top (K_TOP < KXS) part of the atmosphere, the
! model reference state is used to derive the missing heights based
! on the observed pressure with the calibration from the available
! observed heights.
!
! Note:
!
! In case (1), the derived heights have very high accuracy since only
! a high accurate "hydrostatic assumption" used here.
!
! In case (2), the model reference state parameters are used. These
! parameters are consistent with the model BKG, and independent of
! the model domain settings. Of course, the model reference state
! atmosphere is not a real atmosphere, but it's consistent with the model.
! With the observed heights calibrated, these derived heights
! also included some information from OBS (pressure and height).
!
! This subroutine can not be applied to the SIGLE-LEVEL(KXS=1) data.
! For those OBS, the missing heights can only be derived from the
! observed pressure and the model BKG and reference state (subroutine
! recover_hpt).
