One of the most reactive gases in our atmosphere, OH is like a global detergent that helps keep things in balance by removing pollutants from the lower atmosphere. Scientists have numerous questions about OH. For example, continued increases in methane — a potent greenhouse gas — will consume OH, resulting in deteriorated air quality.
In the past, scientists derived estimates of OH by tracking quantities of another trace gas, methyl chloroform, which was widely used in the s as an industrial solvent and was created by bomb blasts during that era. Methyl chloroform only reacts with OH, which slowly destroys it. But methyl chloroform was eventually replaced by other solvents, and over time, its concentrations in the atmosphere have decreased enough that it is no longer useful for estimating OH.
Bowman discussed some of the many other science advances TES has made possible. Its biggest contributions have been in advancing our understanding of ozone in the troposphere. TES data, together with data from other instruments aboard Aura, have significantly improved our understanding of how ozone affects human health, climate and other parts of the Earth system.
A TES study showed how ozone produced in Asia was transported around the world, increasing ozone emissions on the U. West Coast, even as U. Temperatures in the stratosphere increase with altitude. A high concentration of ozone, a molecule composed of three atoms of oxygen, makes up the ozone layer of the stratosphere. This ozone absorbs some of the incoming solar radiation, shielding life on Earth from potentially harmful ultraviolet UV light, and is responsible for the temperature increase in altitude.
The top of the stratosphere is called the stratopause. Temperatures decrease in the mesosphere with altitude. The thermosphere is located above the mesopause and reaches out to around kilometers miles. Not much is known about the thermosphere except that temperatures increase with altitude. The uppermost layer, that blends with what is considered to be outer space, is the exosphere.

The atmosphere protects us from UV and other short wavelength light that would otherwise do a lot of damage to the DNA of living organisms. Without the atmosphere, it would get really hot in the day time, and extremely cold at night! The atmosphere is also important because it contains oxygen, which we and other living organisms breathe.
It also acts as a medium of transport for various chemicals, including, but not limited to, water in the form of rain, snow, steam, etc , carbon dioxide and oxygen for cycling of these chemicals between plants and animals , and nitrogen which helps plants grow. There are also other biogeochemical cycles cycling of different chemicals between the land masses, the oceans, and the atmosphere that are important for the various kinds of ecosystems around the world!
These are only a few of the examples of why the atmosphere is important, but I hope this helps you see why it is important to protect our atmosphere! The atmosphere is important for many reasons. Before we talk about why it is important we should define what the atmosphere is. The atmosphere is the layer of air that surrounds a planet.
Earth has an atmosphere that is just right for humans, animals, and plants to live in. Projects involving students from around the world, of different ages, which allow students to learn new content and release their energy, through participation and discussion. A virtual thematic classroom, high school students linked from various parts of the world for 15 courses on the world of energy, organised by faculty of MIT in Boston and world-renowned experts. We are a partner of the NECST project , the European Union programme that connects schools in Croatia, Holland, Norway and Italy in the creation of a digital platform for research and exchange of knowledge on energy production.
