Stratospheric research focuses on studying the stratosphere, which is the second major layer of Earth's atmosphere located above the troposphere and below the mesosphere. This research area explores various phenomena and processes that occur in the stratosphere, such as the ozone layer, stratospheric circulation, and interactions with other atmospheric layers. Researchers in this field use methods such as satellite observations, ground-based measurements, and climate models to better understand the dynamics and composition of the stratosphere and its implications for weather, climate, and overall atmospheric behavior.
