| 51 | !! |
|---|
| 52 | !! ** Purpose : |
|---|
| 53 | !! This routine computes new vertical grids |
|---|
| 54 | !! in the ice and in the snow, and consistently redistributes |
|---|
| 55 | !! temperatures in the snow / ice. |
|---|
| 56 | !! Redistribution is made so as to ensure to energy conservation |
|---|
| 57 | !! |
|---|
| 58 | !! |
|---|
| 59 | !! ** Method : linear conservative remapping |
|---|
| 60 | !! |
|---|
| 61 | !! ** Steps : 1) Switches |
|---|
| 62 | !! 2) Snow redistribution |
|---|
| 63 | !! 3) Ice enthalpy redistribution |
|---|
| 64 | !! 4) Ice salinity |
|---|
| 65 | !! 5) Inverse temperature computation from enthalpy |
