pres2ahum: Water vapor pressure to absolute humidity.

In ERottler/alptempr: Statistical analysis of alpine climatological data

Description

Calcuation of absolute air humidty based on measurements of water vapor pressure and ambient temperature using formula derived from Ideal gas law. Absolute humidity ahum = vapor_pres / (Rw * tmean) where vapor_pres is the vapor pressure, tmean the ambient temperature and Rw is the specific gas constant and for water equals 461.5 J/(kg*K).

Usage

pres2ahum(vapor_pres, temp, Rw = 461.5)

Arguments

vapor_pres	Vapor pressure [hPa]
temp	Ambient temperature [°C]
Rw	Specific gas constant [J/(kg*K)]

Value

Absolute humidity of air [g/m³].

Examples

pres2ahum(vapor_pres = 5.5, temp = 20)
