Global Electric Circuit movie

Our electric atmosphere has a lot more to it than lightning and thunderstorms. Learn about Earth's Global Electric Circuit and its connection to Space Weather.

Layers of Earth's Atmosphere
Layers of Earth's atmosphere: troposphere, stratosphere, mesosphere, thermosphere and exosphere.
Earth's Atmosphere

Earth's atmosphere is a thin layer of gases that hover above our planet's surface. The atmosphere provides us with oxygen to breathe, shelters us from solar UV radiation, and warms Earth's surface via the greenhouse effect.

About Ozone
Learn about the chemistry of ozone, where it's found in the atmosphere, and how it is both helpful and harmful to life on Earth.

The ozone layer, in the stratosphere, is where about 90% of the ozone in the Earth system is found. But ozone makes up only one to ten out of every million molecules in the ozone layer. There isn't much of it, but ozone is powerful, able to block the most harmful radiation.
