| snice | fraction of box covered with snow or land or ocean ice | unitless |
| oice | ocean or lake ice fraction | unitless |
| uss | surface (10m)u wind | m/s |
| vss | surface (10m) v wind | m/s |
| soil | volumetric water content | m3/m3 |
| snowd | snow depth | mm |
| pardir | direct photosynthetically active radiation | w/m2 |
| pardif | diffusive photosynthetically active radiation | w/m2 |
The albedo is calculated only when sunlight is shining. During a dark timestep, the program "remembers" the albedo from the previous timestep. The problem is that some places are in continuous night.
