The soil moisture index indicates the wetness of the soil. This index is computed using the permanent wilting point and the field capacity, which both depend on the geographical location (soil type). The index is 0 if the permanent wilting point is reached and 1 at field capacity. Note that the index can exceed 1 after rainfall events. The soil moisture index is available for 4 depth levels.
This parameter computes the difference between the actual water content of the soil and the possible water content that the soil can hold in mm. The amount of water that can be hold is called field capacity. The calculation of the SMD is mainly based on soil water information in several depths as well as other meteorological parameters. The SMD is a useful tool in order to assess prevailing soil conditions like droughts. The SMD also depends on the soil type.
This parameter provides the soil type for any location on the globe. The index takes values from 0 to 7, where each number indicates an individual soil type.
Soil temperatures refer to temperatures in various soil depths. In general, soil temperatures depend on the soil type and represent the middle of each layer.
