latent_heat_H2O: Latent heat of vaporization or sublimation of water
In aiRthermo: Atmospheric Thermodynamics and Visualization

Description Usage Arguments Details Value References Examples

This function calculates the latent heat of vaporization or sublimation of water depending as a function of temperature. It uses a polynomial approximation over water or ice.

1	latent_heat_H2O(Temps)

Temps

A vector with temperature values (K).

Taking into account the observed values in tables from Rogers and Yau (1989) and Feistel and Wagner (2006), a polynomial model is used to calculate the latent heat at different temperatures.

This function returns the latent heat of vaporization or sublimation of water.
