| 32 | !! ** Purpose : provide the thermohaline fluxes (heat and freshwater) |
---|
| 33 | !! to the ocean at each time step. |
---|
| 34 | !! |
---|
| 35 | !! ** Method : Read monthly climatological fluxes in a NetCDF file |
---|
| 36 | !! the net downward radiative flux qsr 1 (watt/m2) |
---|
| 37 | !! the net downward heat flux q 2 (watt/m2) |
---|
| 38 | !! the net upward water emp 3 (mm/month) |
---|
| 39 | !! (evaporation - precipitation) |
---|
| 40 | !! the climatological ice cover rclice 4 (0 or 1) |
---|
| 41 | !! |
---|
| 42 | !! Qsr and q is obtained from Esbensen-Kushnir data (opal file) with |
---|
| 43 | !! some corrections : |
---|
| 44 | !! - Data are extended over the polar area and for the net heat |
---|
| 45 | !! flux, values are put at 200 w/m2 on the ice regions |
---|
| 46 | !! - Red sea and Mediterranean values are imposed. |
---|
| 47 | !! |
---|
| 48 | !! emp is the Oberhuber climatology with a function of Levitus |
---|
| 49 | !! salinity |
---|
| 50 | !! |
---|
| 51 | !! rclice is an handmade climalological ice cover on the polar |
---|
| 52 | !! regions. |
---|
| 53 | !! |
---|
| 54 | !! runoff is an handmade climalological runoff. |
---|
