Air Altitude Temperature

Reference data and engineering information about air altitude temperature for gases and compressed air applications.

airaltitudetemperature

Overview

Air temperature and pressure at various altitudes in the International Standard Atmosphere (ISA). The troposphere (0–11 km) has a lapse rate of −6.5°C/km. Above 11 km (tropopause to 20 km), temperature remains constant at −56.5°C.
