atmospheric composition archives

Atmospheric composition archives are records that provide information about the gases and particles present in Earth's atmosphere over time. Scientists create these archives by analyzing ice cores, tree rings, sediments, and other natural materials, which trap and preserve air bubbles from different periods. By studying these samples, researchers can track changes in atmospheric composition, such as levels of greenhouse gases, pollutants, and other key indicators. This information helps us understand climate change, air quality trends, and how human activities impact the environment, ultimately aiding in efforts to protect our planet.
