cal_ActualVapourPressure_from_RHmean {simET}

Calculating actual vapour pressure derived from RHmean

Description

In the absence of RH max and RHmin, it can be used to estimate actual vapour pressure.

Usage

Arguments

RHmean

mean relative humidity(%).

Tmax

daily maximum temperature (degrees Celsius).

Tmin

daily minimum temperature (degrees Celsius).

Value

A vector for actual vapour pressure
