#1199 closed Bug (fixed)

problem in the euphotic layer computation

Description

The condition :

etot(ji,jj,jk) >= 0.0043 * qsr

in p4zopt.F90 can be satisfied even in the land points below the bottom. This is due to the fact that the mask is never considered in the computation of etot. This leads to an overestimation of the euphotic layer in region where the depths are weaks.

This euphotic layer is used in p4zprod.F90 :

zmxltst = MAX( 0.e0, hmld(ji,jj) - heup(ji,jj) )

although, the impact of this bug on the biogeochemical fields is certainly null, it would deserve to be studied with attention.

This bug have been identified in the version 3.2 but is still present in the most recent versions.

Guillaume.
