*author
* Michel Roch - rpn - oct 1993
*
*revision
* v2_00 - Desgagne M. - initial MPI version (from predat1 v1_03)
* v2_30 - Edouard S. - adapt for vertical hybrid coordinate
* v2_31 - Desgagne M. - remove treatment of HUT1 and QCT1
* v3_00 - Desgagne & Lee - Lam configuration
* v3_02 - Desgagne M. - correction for non-hydrostatic version
* v3_03 - Tanguay M. - put v4d_predat inside
* v3_11 - Gravel S. - modify evaluation of Ind_pip, include variable
* topography
* v3_21 - Tanguay M. - do filtering at t=0 in v4d_predat
* v3_21 - Desgagne M. - Revision OpenMP
* v3_22 - Belanger/Lee - Introduce vtap
* v3_22 - Tanguay M. - Change positioning of hzd_hoffld for psd
* v3_30 - Lee V. - remove call to rpn_comm_xch
* v3_31 - Bilodeau B. - Offline mode
*
*object
* Performs preprocessing of the data: part1. We compute:
* dp
* s, pi', q, phi, T staggered, T', phi', pi', ---, (1+d)q', P and T'
* t dpi lin
*
* The model is initialized from an "hydrostatic state".
* For that reason, the computations found in that routine are
* performed considering that:
* dp
* q' = 0, --- = 1 and p = pi.
* dpi
*arguments
