Value

Meaning

Not used

No generation of heat from the soil.

 One source   (z)

Heat production will be estimated based and a base level defined in a parameter table and a sensivitiy parameter in the exponential function. This source is expected to be a chemical source of heat.

HeatProdCoef_A

 One homomogeneous source

Same as above but with a common base level (HeadProcCoef_AA) for each layers.

 Two sources   (z)

Heat production will be estimated based and a base level defined in a parameter table  HeatProdCoef_A2 and biological temperature sensitivy function (Common abiotic Response module). The ONeil function is most appropriate for decreased activity at high temperatures..

Two homomogeneous source

Same as above but with a common base level (HeadProcCoef_AA2) for each layers.
