Air Mass/Density Earthdata

WebAir density can be defined as the number of air molecules per unit volume (number density). Near sea level there are about 2.7x10 19 molecules per cm 3 (cubic centimeter) or 4.4x10 20 molecules per inch 3 (cubic inch). Air molecules are held near the earth by gravity. In other words, air has weight. The 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 (0.0752 lb/cu ft), according to the International Standard Atmosphere (ISA). At 101.325 kPa (abs) and 15 °C (59 °F), air has a density of approx… taktik kleidung
