Radiation Data
Contains the state of the soil surface as an interface between the atmosphere and the soil model.
The surface data files are produced each main output interval (default: 60 min) and represent the general state of the surface at the given model time.
Variable list
This list represents the general variable structure. The actual sequence of the variables might differ but the same information is stored in total.
| Variable | Unit | Description | |
| Index Surface Grid | - | k grid index in which the surface is located (=0 if no DEM is used) | |
| Soil Profile Type | - | Integer Index to the soil profile type used. An additional .SLDX file is generated to be used with LEONARDO to visiualise this information | |
| z Topo | m | Terrain height (relative to reference level) | |
| Surface inclination | ° | Inclination of surface if a DEM is used | |
| Surface exposition | ° | Surface exposition (azimuth) if a DEM is used | |
| Shadow Flag | - | =1 if surface is shaded (max 2% of direct radiation), 0 otherwise | |
| T Surface | °C | Absolute surface temperature | |
| T Surface Diff. | K | Difference surface temperature to reference surface | |
| T Surface Change | K/h | Heating/Cooling rate of surface | |
