Oct 10, 2023 · Near Earth’s surface the pressure decreases with height at a rate of about 3.5 millibars for every 30 metres (100 feet). However, over cold air the decrease in pressure can be much steeper because its density is greater than warmer air. The pressure at 270,000 metres (10 −6 mb) is comparable to that in the best man-made vacuum ever attained.
