Class NetRadiationFromSunHours

java.lang.Object

net.simplace.sim.model.FWSimComponent

net.simplace.sim.components.radiation.fao56.NetRadiationFromSunHours

All Implemented Interfaces:

net.simplace.sim.util.FWSimFieldContainer

public class NetRadiationFromSunHours
extends net.simplace.sim.model.FWSimComponent

Calculates net radiation from sun hours using (FAO 56) methods. Extraterrestrial as well as solar radiation are also calculated.

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