In simET: Tools for Simulation of Evapotranspiration of Field Crops and Soil Water Balance

Actual vapour pressure (ea) derived from psychrometric data

Description

The actual vapour pressure can be determined from the difference between the dry and wet bulb temperatures, the so-called wet bulb depression.

Usage

cal_ActualVapourPressure_from_psychrometricData(Twet, Tdry, P, type)

Arguments

Twet, Tdry	wet bulb depression, with Tdry the dry bulb and Twet the wet bulb temperature (degrees Celsius).
P	is the atmospheric pressure (kPa).
type	psychrometer type ("Asmann type","natural ventilated","non-ventilated").

Value

A vector for Actual vapour pressure (ea)
