actual_vp: Estimate actual vapor pressure.

In Sibada/sibadaR: Sibada's accumulated R scripts for next probably use to avoid reinventing the wheel.

Description

Estimate actual vapor pressure by providing daily maximum and minimum air temperature, daily maximum, mean and minimum relative humidity.

Usage

actual_vp(tmin, tmax = NULL, rhmax = NULL, rhmean = NULL, rhmin = NULL)

Arguments

tmin	Daily minimum air temperature at 2m height [deg Celsius].
tmax	Daily maximum air temperature at 2m height [deg Celsius].
rhmax	Daily mean relative humidity [%].
rhmean	Daily mean relative humidity [%].
rhmin	Daily mean relative humidity [%].

Details

tmin must be provided. If tmax was not provided, avp will only estimated by tmin. If both rhmax and rhmin are provided, avp will be estimated by tmax, tmin, rhmax and rhmin. If rhmin was not provided but provided rhmean, avp will estimated by rhmean, tmax and tmin. If rhmin and rhmean are not provided, avp will estimated by rhmax, tmax and tmin. If rhmax, rhmean and rhmin are not provided, avp will only estimated by tmin.

Value

Actual vapor pressure (i.e. avp or ea) [kPa].
