The International Standard Atmosphere (ISA) is a static atmospheric model of how the pressure, temperature, density, and viscosity of the Earth's atmosphere change over a wide range of altitudes or elevations. Aviation standards and flying rules are based on the International Standard Atmosphere. Cookies are only used in the browser to improve user experience. It has been revised from time to time since the middle of the 20th century. 398 Appendix B Table B.2 Properties of the International Standard Atmosphere (ISA) between sea level and 20 km geopotential altitude Standard values at altitude Alt. It has the same model as the ISA, but extends the altitude coverage to 80 kilometers (262,500 feet).The ICAO Standard Atmosphere, like the ISA, does not contain water vapor. Non-standard (hot or cold) days are modeled by adding a specified temperature delta to the standard temperature at altitude, but pressure, density, and viscosity are The International Civil Aviation Organization (ICAO) published their "ICAO Standard Atmosphere" as Doc 7488-CD in 1993.

The U.S. Standard Atmosphere is a static atmospheric model of how the pressure, temperature, density, and viscosity of the Earth's atmosphere change over a wide range of altitudes or elevations.The model, based on an existing international standard, was first published in 1958 by the U.S. Committee on Extension to the Standard Atmosphere, and was updated in 1962, 1966, and 1976. Please read If you want to promote your products or services in the Engineering ToolBox - please use The ISA mathematical model divides the atmosphere into layers with an assumed linear distribution of absolute temperature T against geopotential altitude h. The other two values (pressure P and density ρ) are computed by simultaneously solving the equations resulting from:
