Atmospheric structure refers to the vertical distribution of temperature, pressure, and density in the Earth's atmosphere. This research area focuses on studying how these key atmospheric variables change with altitude, and how they influence weather patterns, climate, and other meteorological phenomena. Researchers in this field use a combination of observational data, satellite measurements, and computer models to analyze and understand the complex structure of the atmosphere, from the surface to the edge of space. By studying atmospheric structure, scientists can better predict and respond to weather events, track changes in the climate, and improve our understanding of Earth's atmospheric processes.
