net.simplace.client.simulation.lap.fao56.radiation.SolarRadiationFromTemperature

Calculates Solar radiation from max and min temperatures using (FAO 56) methods.

The AdjustmentCoefficient should range between 0.16 and 0.19. Default value is 0.17037037037037037037 - so when this module is combined with ReferenceETHargreaves module the combination gives Hargreaves & Sarmani 1985 formula.

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