vp_sat_curve_slope: Slope of saturation vapour pressure curve

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

Description

Calculates the slope of the saturation vapour ressure curve (i.e., the slope of the relationship between saturation vapour pressure and temperature) based on Equation 13 in Allen et al. (1998).

Usage

vp_sat_curve_slope(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

Delta

slope of the saturation vapour pressure curve at the given air temperature
