WebThe air is assumed to be a perfect gas. In the lower region, the troposphere, the atmosphere has a lapse rate (L) of 6.5K/Km. At an altitude of 36089 ft the stratosphere starts and the temperature remains constant at 217K. The hydrostatic equation, perfect gas law and the lapse rate equation are WebPressure Altitude Formula is given by the equation P = P₀ exp (-gM (h-h₀)/ (RT)) h is the altitude at which we want to determine the air pressure and is expressed in units m. P is the air Pressure at Altitude h. P₀ is the pressure at reference level h₀. In general, reference level is at sea level and h₀ = 0. T is the Temperature at ...
Web1 Answer. Sorted by: 3. The volume of carbon dioxide in the atmospheric column becomes uniform at altitude because the sources and sinks for CO2 are generally at ground level and, as it rises, CO2 becomes well-mixed into the atmosphere. This is why, for example, David Keeling began the measurements for what would become known as the Keeling ...
