saturation_pressure_H2O: Saturation Pressure

Description

This function returns the saturation pressure (Pa) from a given array of temperatures (K). It uses approximate equations 5.67 and 5.70 in Bohren Albrecht, 1998.

Usage

saturation_pressure_H2O(Temps)

Arguments

Temps

A vector with temperature values in Kelvin

Value

This function returns a vector with saturation pressure values (Pa)

Details

Saturation pressure of water vapour \(e_s\) is computed over ice/water depending whether the temperature is over/under 273.15 K (0 degree Celsius) at every element of the array.
