Atmospheric physics is a branch of meteorology and physics that focuses on the study of the Earth's atmosphere and how it interacts with other systems such as oceans, land, and living organisms. Researchers in this field study various atmospheric phenomena such as weather patterns, climate change, air pollution, and the behavior of gases and particles in the atmosphere. They use tools such as computer models, satellite data, and observational data to better understand and predict atmospheric processes. The ultimate goal of atmospheric physics research is to improve our understanding of the Earth's atmosphere and its impact on human society and the environment.
