c    ngrid                 Size of the horizontal grid.
c                          All internal loops are performed on that grid.
c    nlayer                Number of vertical layers.
c    pdayref               Day of reference for the simulation
c    firstcall             True at the first call
c    lastcall              True at the last call
c    pday                  Number of days counted from the North. Spring
c                          equinoxe.
