About Air Temperature vs Altitude
Air temperature varies with altitude in the Earth's atmosphere following the International Standard Atmosphere (ISA) model. Temperature decreases in the troposphere with increasing altitude, stabilizes in the lower stratosphere, and then shows variable trends through the mesosphere and thermosphere. Understanding the temperature profile is crucial for aerospace engineering, thermodynamics, meteorology, and fluid mechanics.
Accurate knowledge of air temperature at different altitudes is essential for applications such as aircraft performance calculations, rocket trajectory planning, HVAC design at high altitudes, and environmental modeling. It also influences air density, pressure, and other atmospheric properties critical for engineering and scientific analysis.
The table and graph on this page provide a clear reference of air temperature as a function of altitude in SI units, covering the range from sea level to 100 km. This reference supports engineers, scientists, and educators in performing thermodynamic calculations, aerodynamic simulations, and atmospheric studies.
Engineers and researchers can combine this temperature-altitude data with other atmospheric properties such as pressure, density, and specific gas constant to model air behavior in flow systems, propulsion systems, and climate simulations.
