What Is The Volume Of Earth’s Atmosphere?

The volume of Earth’s atmosphere is estimated to be around 5140 trillion tonnes. This makes the atmosphere much larger than the planet’s surface. Note that the figure can only be estimated, as the atmosphere is constantly changing due to weather patterns and other natural phenomena.

The majority of the air that we breathe is contained in the troposphere, which extends from sea level up to about 10 kilometers. Above this layer lies the stratosphere, mesosphere and thermosphere.

The atmosphere also contains a variety of gases, including nitrogen (78%), oxygen (21%) and other trace gases such as argon, carbon dioxide and water vapor. These gases form the basis of Earth’s protective ozone layer, vital for protecting us from harmful ultraviolet radiation.

The atmosphere also contains aerosols and clouds, made up of tiny particles suspended in the air. These small particles can help to reflect sunlight, thereby cooling the climate on Earth. Overall, Earth’s atmosphere is a complex and dynamic system essential for life on our planet.

What Is the Volume of the Troposphere?

Because of gravity,  the atmosphere becomes increasingly thinner as altitude increases. The troposphere is the lowest layer of Earth’s atmosphere, containing approximately 80% of all air on Earth, including most weather phenomena. 

The total volume of the troposphere is estimated to be around 6 × 109 cubic km. This means that the atmosphere at sea level is much denser than higher up since air molecules are compressed by gravitational forces close to Earth’s surface.


Earth’s atmosphere is a huge and complex system that plays an integral role in our planet’s climate. Although it is quite impossible to measure its exact volume, based on estimates, the atmosphere is estimated to be around 5140 trillion tonnes.
