What is the air pressure in the troposphere?

The troposphere is the lowest layer of the earth's atmosphere and is the one that contains weather and which can support life. Its upper limit is the highest point that the suns heat can cause warm and moist air to reach. read more

The average depths of the troposphere are 18 km (11 mi) in the tropics, 17 km (11 mi) in the mid latitudes, and 6 km (3.7 mi) in the polar regions in winter. The lowest part of the troposphere, where friction with the Earth's surface influences air flow, is the planetary boundary layer. read more

Air pressure in the lowest layer, or troposphere, is much greater than the air pressure in the thermosphere, which sits on the edge of space. Air Pressure Fundamentals As the National Weather Service reports, air pressure is considerable if you sum the forces that molecules in all the atmospheric layers exert. read more
