[[ParentLinkage(=)]] = '''New Surface Module''' = We put here description of the work done around this package. Mainly some figures ...etc '''CONTEXT:'''[[BR]] ''Experiments:'' REF_CORE (reference version) & SBC_NEW (new surface module)[[BR]] ''Configuration type'': Configuration ORCA2_LIM with bulk CORE[[BR]] "Forcing spefs:" precipitation and snow are monthly value without time interpolation else [[BR]] it will be different in SBC_NEW and REF_CORE. '''In T2X experiences''':[[BR]] In doing the following modifications in both experiments, we are waiting for almost exactly the same results.[[BR]] # The wind stress ([uv]tau/gtau[xy]) and wind module (zwind_speed_t(:,:)/dUnormt(:,:) at the ocean surface (even [[BR]] above sea-ice) is forced to be the same in both experiments. (sbcblk_core.F90/flx_core.h90)[[BR]] # The friction velocity ust2s(:,:) between sea-ice and ocean is also forced to be the same (limdyn.F90)[[BR]] '''In FULL experience''': done for REF_CORE and SBC_NEW: [[BR]] We fully relax constrains imposed in T2X experiences, i.e. on stress, frictional velocity and so on ... '''In FULL_SDP experience''':[[BR]] similar to FULL but with a strong restoring SSS damping of ~ 787 mm/day correponding to 12 days of time restoring [[BR]] It is the same time damping as the SST which corresponds to -40 W/m2/K used for SST over a 10 meters ocean water column.[[BR]] Modifications have been necessary in sbcssr.F90 module such as using the array sdta(:,:) computed in dtasal.F90 to ensure same [[BR]] SSS damping field in both experiments SBC_NEW and REF_CORE.[[BR]] '''In FULL_SDP2 experience''':[[BR]] Still SSS damping term without the ice-dynamics, i.e. ln_limdyn=.FALSE. in the sea-ice namelist. '''In FULL_SDP3 experience''':[[BR]] Only for the SBC_NEW code, this time this run is identical to FULL_SDP but in sbcblk_core.F90, the sea-ice velocity ([uv]i_ice()) has been removed in the computation of the wind stress and wind module over sea-ice.[[BR]] Since the computation is clearly done in a better way now, it could implies important modifications which should be identify. ---- == '''FULL_SDP Experiences''': == '''Ice thickness in NEW_SBC experience / Year 10'''[[BR]] The sea-ice extension in winter seems to be larger in this run than in the REF_CORE one.[[BR]] [[Image(FULL_SDP_SBC_NEW_icethic_March_Arctic.png, 90%)]] ---- '''Ice thickness in REF_CORE experience / Year 10'''[[BR]] [[Image(FULL_SDP_REF_CORE_icethic_March_Arctic.png, 90%)]] ---- '''Ice thickness in NEW_SBC experience / Year 10''': NO SEA-ICE DYNAMICS = ln_limdyn=FALSE[[BR]] [[Image(FULL_SDP2_SBC_NEW_icethic_March_Arctic.png, 90%)]] ---- '''Ice thickness differences between NEW_SBC & REF_CORE experience / Year 10''': NO SEA-ICE DYNAMICS = ln_limdyn=FALSE[[BR]] [[Image(FULL_SDP2_SBC_NEW_REF_CORE_icethic_March.png, 90%)]] ---- == '''T24 Experience''': == '''Ice thickness in NEW_SBC experience / Date 11/2000'''[[BR]] Image(T24_Icethic_New_Polaire_112000.png, 90%) ---- '''Ice thickness differences between NEW_SBC - REF_CORE / Date 11/2000 '''[[BR]] Image(T24_Icethic_New_T24_Icethic_Ref_Polaire_112000.png, 90%) ---- '''SSS differences between NEW_SBC - REF_CORE / Date 11/2000'''[[BR]] Image(T24_S_New_T24_S_Ref_112000_Global.png, 90%) ---- '''SST differences between NEW_SBC - REF_CORE / Date 11/2000'''[[BR]] Image(T24_T_New_T24_T_Ref_112000_Global.png, 90%) ---- '''Net heat flux at the sea-ice base differences between NEW_SBC - REF_CORE / Date 11/2000'''[[BR]] Image(T24_oceflxb_New_T24_oceflxb_Ref_112000_Global.png, 90%) ---- '''EmP differences between NEW_SBC - REF_CORE / Date 11/2000'''[[BR]] Image(T24_EmP_New_T24_EmP_Ref_112000_gloabl.png, 90%) ---- == '''T16 experience''' == '''Net heat flux at the sea-ice base differences between NEW_SBC - REF_CORE''' Image(T16_oceflxb_New_T15_oceflxb_Ref_112000_Global.png, 90%) ---- '''SSS differences between NEW_SBC - REF_CORE''' Image(T16_S_New_T15_S_Ref_112000_Global.png, 90%) ---- '''SST differences between NEW_SBC - REF_CORE''' Image(T16_T_New_T15_T_Ref_112000_Global.png, 90%) ---- '''EmP differences between NEW_SBC - REF_CORE''' Image(T16_EmP_New_T15_EmP_Ref_112000_Global.png, 90%) ---- '''Ice Thickness differences between NEW_SBC - REF_CORE''' Image(T16_Icethic_New_T15_Icethic_Ref_112000_Global.png, 90%)
