# Problem ok_freeze in hydrol.f90

Reported by: Owned by: maignan maignan major IPSLCM6.v1 Physical processes trunc

In the following parts under IF ok_freeze ELSE, the jst index should always appear instead of : on the third dimension as we are in a loop over jst:

```3991	    !
3992	    !! -- START MAIN LOOP OVER SOILTILES
3993	    !!    The called subroutines work on arrays with DIMENSION(kjpindex), recursively used for each soiltile jst
3994	    !
3995	    DO jst = 1,nstm
...
4162       IF (ok_freeze_cwrr) THEN
4163	          DO ji =1, kjpindex

4165	                mcl(ji,jsl,:)= MIN(mc(ji,jsl,:),mcr(njsc(ji))+(1-profil_froz_hydro_ns(ji,jsl, :))*(mc(ji,jsl,:)-mcr(njsc(ji))))

### comment:2 Changed 5 years ago by maignan

In hydrol_soil, prior to any use of profil_froz_hydro_ns, a:

CALL hydrol_soil_coef(kjpindex,jst,njsc)

has to be made to update profil_froz_hydro_ns in the possible case where mc has been modified.
In rev [2928], this concerns lines 4197, 4539 for sure.
It's not always easy to see when mc is modified because it can be done in any subroutine as mc is a global variable.
The best solution would be to make a systematic call, as ulterior modifications may again modify mc between a call to hydrol_soil_coef and the following use of profil_froz_hydro_ns.
This would also concern lines 4272, 4804, 4883.
