sat_vapor_density: Saturation vapor density

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

Description

Calculates the saturation vapor density from the ideal gas law based on Equation 2.6 in Harwell (2012).

Usage

sat_vapor_density(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

svd	saturated vapor density (g/m^3)
