About 90% of total ozone in the atmosphere is in the stratosphere, and 10% is in the troposphere. [5] Although ground-level ozone is less concentrated than stratospheric ozone, it is of concern because of its health effects. [6] Ozone in the troposphere is considered a greenhouse gas, and as such contribute to global warming.
The gas layers of the troposphere are less dense at the geographic poles and denser at the equator, where the average height of the tropical troposphere is 13 km, approximately 7.0 km greater than the 6.0 km average height of the polar troposphere at the geographic poles; therefore, surplus heating and vertical expansion of the troposphere ...
Ozone in the troposhere is determined by photochemical production and destruction, dry deposition and cross-tropopause transport of ozone from the stratosphere. [2] In the Arctic troposphere, transport and photochemical reactions involving nitrogen oxides and volatile organic compounds (VOCs) as a result of human emissions also produce ozone resulting in a background mixing ratio of 30 to 50 ...

The troposphere is denser than all its overlying layers because a larger atmospheric weight sits on top of the troposphere and causes it to be most severely compressed. Fifty percent of the total mass of the atmosphere is located in the lower 5.6 km (3.5 mi; 18,000 ft) of the troposphere.
Methane increases the amount of ozone (O 3) in the troposphere (4 miles (6 km) to 12 miles (19 km) from the Earth's surface) and also in the stratosphere (from the troposphere to 31 miles (50 km) above the Earth's surface). [20] Both water vapour and ozone are GHGs, which in turn add to climate warming. [6]: 2
Of the vertically developed clouds, the cumulonimbus type is the tallest and can virtually span the entire troposphere from a few hundred metres above the ground up to the tropopause. [33] It is the cloud responsible for thunderstorms. Some clouds can form at very high to extreme levels above the troposphere, mostly above the polar regions of ...
