Liquid non-frozen volumetric soil moisture

Sea points should be set as missing values.

To interpret soil moisture and to compare different models the Soil Wetness Index (SWI) is used:
SWI = (soil_moisture - wilting_point) / (field_capacity - wilting_point).

Field capacity corresponds to the maximum value that the model can sustain without precipitation for more than a few hours. The vegetated fraction of the soil evaporates at the maximum rate for soil moisture larger than field capacity and stops evaporating below the permanent wilting point, with a continuous variation between the two extremes.
All Partners are asked to provide the wilting point and the field capacity for each grid point.
