Numerical table based on the barometric levelling model. Calculated values represent the average state of the atmosphere.
Warning: season, latitude and weather conditions influence atmospheric temperature.
Example of table reading: What is the average temperature of the atmosphere at an altitude of 1800 m ?
The decomposition 1800 = 1500 + 300 brings us to the intersection of the 1500 m line and the 300 m column, where we read the temperature of 3.3 °C.
