net.simplace.sim.transformers.NetRadiationFromAnyTransformer

Calculates net radiation from either global radiation or, if no global radiation available, from sun hours using (FAO 56) methods. Extra-terrestrial as well as solar radiation (in case of sun hours input) are also calculated.

Chosen method depends on input availability, preferential order as below.

From solar radiation.
From sun hours.

Note: If data is missing in weather inputs, calculation method may change without throwing an error. This may be desired when dealing with an incomplete dataset, but undesired when missing data unintendedly changes the calculation method. An INFO message is written to log when the method changes.

For documentation of the formulas please check the original reference (FAO 56)
