LIM3 bug: wrong value of fresh water budget sent to passive tracers (fmmflx)

Reported by: clem Owned by: nemo
Priority: normal Milestone:
Component: OCE Version: v3.6
Severity: Keywords:


In LIM3 (limsbc.F90), the fresh water budget recorded to dilute/concentrate passive tracers (fmmflx) is divided by the ice time step (rdt_ice) while it should not.

fmmflx(ji,jj) = - ( wfx_ice(ji,jj) + wfx_snw(ji,jj) + wfx_err_sub(ji,jj) ) * r1_rdtice

The ice freeze/melt has therefore basically no effect on passive tracers. The right flux is (in kg.m-2.s-1):

fmmflx(ji,jj) = - ( wfx_ice(ji,jj) + wfx_snw(ji,jj) + wfx_err_sub(ji,jj) )

This flux is also used for a parameterization of the iron uptake by the ice (not sure it is activated??)
