Conversion to Volumetric Water Content

Third step of the data processing chain.

Next is the conversion of microwave brightness temperature into volumetric water content.

Skaha's land-surface model (LSM) is used to calculate the average field moisture level. Details about the process can be found in the LSM documentation.

If the dataset is for a new field, calculating the average soil moisture can take several hours. The calculation takes only a few seconds if the meteorological, satellite, and soil data have already been obtained.

Below is an example of a field calibrated in brightness temperature $T_B$ (left) and volumetric water content (right). Since we assume a linear relation between the two, the only change between the two is in the units.
