Atmospheric science is the study of the Earth's atmosphere and its various inner-working physical processes. Meteorology includes atmospheric chemistry and atmospheric physics with a major focus on weather forecasting.

The atmosphere is a mixture of gases that surrounds the planet. Without the atmosphere, life on Earth wouldn't be possible.

The atmospheric sciences are traditionally divided into three topical areas— meteorology (the study and forecasting of weather), climatology (the study of long-term atmospheric patterns and their influences), and aeronomy (the study of the physics and chemistry of the upper atmosphere).

Mar 22, 2025 · Atmosphere, the gas and aerosol envelope that extends from the ocean, land, and ice-covered surface of a planet outward into space. The density of the atmosphere decreases outward, because the planet’s gravitational attraction, which pulls the gases and aerosols inward, is greatest close to the surface.

May 13, 2024 · When we talk about the Earth's Atmosphere, what do we mean? Imagine a layer cake, wrapping around the Earth. That is essentially what the Earth’s atmosphere is like: layers upon layers of gas surrounding the Earth, working to protect the planet.

Dec 9, 2024 · Meteorology is the study of the atmosphere, atmospheric phenomena, and atmospheric effects on our weather. The atmosphere is the gaseous layer of the physical environment that surrounds a planet. Earth’s atmosphere is roughly 100 …

Feb 27, 2025 · Atmospheric science is the study of the dynamics and chemistry of the layers of gas that surround the Earth, other planets and moons.

This article provides an atmospheric science definition to help increase your understanding of the field, an overview of why it is important, and information on how atmospheric scientists are working to lessen the impacts of climate change.

Sep 24, 2009 · Atmospheric Science is the study of the composition and structure of the atmosphere using tools from fluid dynamics, chemistry, statistics, and other sciences. From: Reference Module in Earth Systems and Environmental Sciences, 2013

Oct 6, 2023 · The atmosphere of the earth is the layer of gases (commonly called air) that surrounds the earth and creates an inhabitable environment, maintains temperature, causes weather, and protects its inhabitants from solar radiation.
