The Sucros2 sim component is split into a crop and water module. Potential and actual evapotranspiration are calculated in the water module
There is an alternative splitting where potential evapotranspiration is calculated in the crop module, actual evapotranspiration in the water module
For detailed information about the Sucros2 model please consult the original documentation (S).
The combination of the split submodules gives slightly different results than the whole sim component Sucros2. There are differences in the two splittings too.
The order in which the split submodules are combined also matters.
