Vapor pressure over liquid surface can be calculated from a variety of different combinations of state variables. Here, vapor pressure is calculated from mixing ratio w (kg/kg) and pressure P. Formula is given in standard literature; e.g. eq. 2.18 in Rogers&Yau (Cloud physics) and eq. 4.1.2 in Emanuel (1994). Reference: * Emanuel, K. A. (1994): Atmospheric Convection. New York, NY:
