3!-------------------------------------------------------------------------------
4! Authors: P. Le Van , Fr.Hourdin
5!-------------------------------------------------------------------------------
6! Purpose: Compute pressure p(l) at different levels from l = 1 (ground level)
7!          to l = llm +1. Those levels correspond to the llm layers interfaces,
8!          with p(ij,llm+1) = 0. and  p(ij,1) = ps(ij)  .

14! Arguments:
15  INTEGER, INTENT(IN)  :: ngrid                 !--- NUMBER OF GRID POINTS
16  REAL,    INTENT(IN)  :: ap(llmp1), bp(llmp1)  !--- HYBRID COEFFICIENTS
17  REAL,    INTENT(IN)  :: ps(ngrid)             !--- SURFACE PRESSURE
18  REAL,    INTENT(OUT) :: p(ngrid,llmp1)        !--- 3D PRESSURE FIELD
