The water vapour content of the air
WebThe density of air or atmospheric density, denoted ρ, is the mass per unit volume of Earth's atmosphere.Air density, like air pressure, decreases with increasing altitude. It also changes with variation in atmospheric pressure, temperature and humidity.At 101.325 kPa (abs) and 20 °C (68 °F), air has a density of approximately 1.204 kg/m 3 (0.0752 lb/cu ft), according … WebThe water vapor mixing ratio, w, is typically at most about 40 g kg –1 or 0.04 kg kg –1, so even for this much water vapor, q = 0.040/ (1 + 0.040) = 0.038 or 38 g kg –1. Thus, water vapor mixing ratio and specific humidity are the same to within a few percent.
