- 1. Atmospheric science, also known as meteorology, is a scientific field that focuses on the study of the Earth's atmosphere and its interactions with various systems. It involves the observation, analysis, and prediction of atmospheric phenomena such as weather patterns, climate change, air quality, and the behavior of gases in the atmosphere. Atmospheric scientists use a variety of tools and techniques, including satellite data, weather stations, computer models, and statistical analysis, to better understand the complex dynamics of the atmosphere. By studying atmospheric science, researchers can improve weather forecasts, assess environmental impacts, and contribute to a better understanding of our planet's climate system.
