**Soil Data** 

Contains the state of the soil data for every simulation output. 
Note that the file is structured top to bottom: The first z is the first soil layer below the surface followed by the next deeper layer for z=2 etc.

<WRAP clear></WRAP>

The soil data files are produced each main output interval (default: 60 min) and represent the general state of the soil at the given model time.

==== Variable list ====

<fs x-small>This list represents the general variable structure. The actual sequence of the variables might differ but the same information is stored in total.</fs>


|  |**Variable** |**Unit** |**Description** |
|  |Temperature| °C | Absolute Temperature of soil layer |
|  |Volumetric Water Content| m³(Water)/m³(Soil) | Amount of liquid water per cube meter soil|
|  |Relative Soil Wetness related to sat| % | Amount of liquid water relative to the soils saturation value|
|  |Available Water Capacity | % | Plant usable water in soil layer in percent. (Amount of plant extractable water related to the maximum possible amount of plant extractable water [[wp>Available_water_capacity]]) $$ AWC(rel) = \frac{ \theta- \theta_{pwp}} {\theta_{fc} - \theta_{pwp} } $$|
|  |Local RAD | m²/m³ | Root Surface Area per cube meter soil|
|  |Local RAD Owner| - | List index of plant "owning" the roots in this cell. (Only one plant can have roots in one cell. If several plants compete for one grid, the plant with the highest local RAD wins|
|  |Root Water Uptake | g(Water)/m³(Soil)*1/s | Water extracted by the plant root in this cell|
