[MITgcm-devel] Updating initial SSH

[Wang, Ou (329B)]

Hi Gael,

We noticed in the newest code in CVS that when the initial ssh control is turned on, the initial ssh adjustment is only added to ssh at one time-level (etaN), not etaH (lines 80-81 in ctrl_map_ini_genarr.F<http://mitgcm.org/viewvc/MITgcm/MITgcm/pkg/ctrl/ctrl_map_ini_genarr.F?hideattic=0&revision=1.22&view=markup> as attached below).
   if (igen_etan.GT.0)
&  call ctrl_map_genarr2d(etaN,igen_etan,myThid)

We think etaH should also be updated. What do you think? In fact, in old versions of the code both etaN and etaH of ssh at two-time levels got updated in (lines 509 to 512 in ctrl_map_ini.F<http://mitgcm.org/viewvc/MITgcm/MITgcm/pkg/ctrl/ctrl_map_ini.F?hideattic=0&revision=1.45&view=markup>)
   etaN(i,j,bi,bj) = etaN(i,j,bi,bj) +
& fac*tmpfld2d(i,j,bi,bj)
   etaH(i,j,bi,bj) = etaH(i,j,bi,bj) +
& fac*tmpfld2d(i,j,bi,bj)

Thanks,
Ou
