The early atmosphere of the Earth was very different from the atmosphere today! Stage I (Primordial Atmosphere): ♦ Acquired by gravitational attraction of volatile gases from the proto planetary nebula of the Sun ♦ Consisted mostly of H2 and He ♦ Small and warm planets (Earth, Mars, Venus, Mercury) lost this atmosphere because the gravity ...

The climate cycle is a complicated system of components that absorb and reflect solar radia- tion. Around 342 watts per square meter (W/m2) of solar radiation enters Earth’s atmosphere, and the same amount reradi- ates back from the planet, but this radiation takes many detours along the way. It can get trapped in clouds or reflected by clouds, absorbed by Earth’s surface in some places ...

The atmosphere is the thin envelope of gas molecules surrounding the Earth; it is held down by Earth’s gravitational pull. The atmosphere is concentrated at the Earth’s surface and rapidly thins as you move upward, blending with space at about 100 miles above sea level.

Oct 19, 2023 · Earth’s atmosphere is so much more than the air we breathe. A trip from the surface of Earth to outer space would result in passing through five different layers, each with very different characteristics.
Chapter 1 presents an overview of the Earth-atmosphere system, describing its composition, structure, and energetics. It culminates in a discussion of global mean temperature, its relationship to atmospheric composition, and issues surrounding uncertainties in instrumental and proxy records of climate.
