vp_sat_mean: Vapour pressure, mean saturated

In WDNR-Water-Use/CSLSevap: Evapo(transpi)ration Calculations

Description

Calculates the mean saturation vapour pressure for an hourly, daily, or larger time period based on Equations 11 and 12 of Allen et al. (1998).

Usage

vp_sat_mean(atmp)

Arguments

atmp	air temperature (degrees C). When dt is "daily" or larger, argument should be a list with elements "min" and "max" for daily min and max temperatures. When dt is "hourly", argument should be a vector with hourly recorded temperatures.

Value

es	mean saturation vapour pressure (kPa) during time period of interest
