*
***s/r ainmi_ptend  - Adjoint of inmi_ptend.ftn. Used by INMI approach.
*
*Author  : Luc Fillion - 8 May 2007.
*Revision:
* Luc Fillion - ARMA/EC - May 2010 - Implement in v_11_01b.
*
*     -------------------
**    Purpose: Used for LAM4D analysis
*
*Arguments
*
* input sensitivity:
*     pvort    = Vertically projected vorticity time-tendency
*     pdiv     = Vertically projected Divergence time-tendency
*     pp       = Vertically projected P mass time-tendency
*
* output sensitivity:
*     pvort    = Vorticity time-tendency on physical vertical grid.
*     pdiv     = Divergence time-tendency on physical vertical grid.
*     pgz      = GZ time-tendency on physical vertical grid.
*     plnps    = Lnps time-tendency on physical grid.
