Minor bug in PISCES

Description

Context

2 minor bugs have been identified in PISCES model :

  • the time-step used to compute PISCES 3D trends is wrong.
  • the need to include a threshold values to avoid huge concentration, especially on river mouths

Analysis

The tracer time-step rfact ( rather than rfact2) must be used to compute the 3D PISCES trend, since all the biological processes have been already included in trb(:,:,:,:)

Recommendation

In routine p4zsms.F90, simply change the line

ztrdt(:,:,:,jn) = ( trb(:,:,:,jn) - ztrdt(:,:,:,jn) ) * rfact2r 

with

ztrdt(:,:,:,jn) = ( trb(:,:,:,jn) - ztrdt(:,:,:,jn) ) * rfactr
