dewpoint: Dew-point temperature (t_d)

In jinlee86/bems_analysisr_package: EDAS System R Package

Description

Calculates the dew-point temperature based on humidity ratios. Eq. 37 & 38 - ASHRAE Fundamentals Handbook 2002, Psychrometrics.

Usage

dewpoint(hum.ratio, alt = 0)

Arguments

hum.ratio	Vector of humidity ratios [kg/kg].
alt	Vector of altitudes [m]. Defaults to 0 m (sea level).

Value

Returns a vector of dew-point temperatures [degC].
