WebAir temperature affects the movement of air, and thus the movement of air pollution. Because energy from the Sun is absorbed by the Earth's surface, air near the ground is warmer than air that is farther up in the troposphere. The warmer, lighter air at the surface rises, and the cooler, heavier air in the upper troposphere sinks. WebAbsolute humidity (AH) : AH, kg/m³ = P w ⁄ (R w × T) where P w is the water vapor pressure, T is ambient temperature in Kelvin, R w is specific gas constant for water vapor and it is equal to 461.5.
