|---|

|---|
| 786 | !! or at a same point (T or I) if received on 1 grid |

|---|
| 987 | !! |
|---|
| 988 | !! ** Method : transform the fields received from the atmosphere into |
|---|
| 989 | !! surface heat and fresh water boundary condition for the |
|---|
| 990 | !! ice-ocean system. The following fields are provided: |
|---|
| 991 | !! * total non solar, solar and freshwater fluxes (qns_tot, |
|---|
| 992 | !! qsr_tot and emp_tot) (total means weighted ice-ocean flux) |
|---|
| 993 | !! NB: emp_tot include runoffs and calving. |
|---|
| 994 | !! * fluxes over ice (qns_ice, qsr_ice, emp_ice) where |
|---|
| 995 | !! emp_ice = sublimation - solid precipitation as liquid |
|---|
| 996 | !! precipitation are re-routed directly to the ocean and |
|---|
| 997 | !! runoffs and calving directly enter the ocean. |
|---|
| 998 | !! * solid precipitation (sprecip), used to add to qns_tot |
|---|
| 999 | !! the heat lost associated to melting solid precipitation |
|---|
| 1000 | !! over the ocean fraction. |
|---|
| 1001 | !! ===>> CAUTION here this changes the net heat flux received from |
|---|
| 1002 | !! the atmosphere |
|---|
| 1003 | !! |
|---|
| 1004 | !! N.B. - fields over sea-ice are passed in argument so that |
|---|
| 1005 | !! the module can be compile without sea-ice. |
|---|
| 1006 | !! - the fluxes have been separated from the stress as |
|---|
| 1007 | !! (a) they are updated at each ice time step compare to |
|---|
| 1008 | !! an update at each coupled time step for the stress, and |
|---|
| 1009 | !! (b) the conservative computation of the fluxes over the |
|---|
| 1010 | !! sea-ice area requires the knowledge of the ice fraction |
|---|
| 1011 | !! after the ice advection and before the ice thermodynamics, |
|---|
| 1012 | !! so that the stress is updated before the ice dynamics |
|---|
| 1013 | !! while the fluxes are updated after it. |
|---|
| 1014 | !! |
|---|
