net.simplace.sim.components.vapourpressure.fao56.VapourpressureFromRelHumidityMean

Calculates vapour pressure from mean relative humidity by (FAO 56) method.

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

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