deltaVP: Slope of the saturation vapor pressure curve

In MeTo: Meteorological Tools

Slope of the saturation vapor pressure curve

Description

Slope of the saturation vapor pressure curve [kPa/degreeC].

Usage

deltaVP(Tmean = NULL, Tmax = NULL, Tmin = NULL)

Arguments

Tmean	Mean Temperature [degreeC] (mean daily, mean hourly, etc. air temperature)
Tmax	maximum temperature during 24-hour period [degreeC] (if Tmean is missing)
Tmin	minimum temperature during 24-hour period [degreeC] (if Tmean is missing)

Details

valid for daily, hourly and shorter periods

Value

slope of the saturation vapor pressure curve [kPa/degreeC]
