Class VapourpressureFromRelHumidityMaxMin

java.lang.Object
net.simplace.sim.model.FWSimComponent
net.simplace.sim.components.vapourpressure.fao56.VapourpressureFromRelHumidityMaxMin
All Implemented Interfaces:
net.simplace.sim.util.FWSimFieldContainer
public class VapourpressureFromRelHumidityMaxMin extends net.simplace.sim.model.FWSimComponent
Calculates vapour pressure from min and max relative humidity by (FAO 56) method.

Needs min and max humidity, min and max temperature as input.

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