Overview
Atmospheric Composition includes variations in and processes that affect aerosols, clouds, and trace gases, which influence climate, weather, and air quality. AC provides observations and modeling tools to assess the effects of climate change on ozone recovery and future atmospheric composition; improve climate forecasts based on fluctuations in global environmental change; and model past, present, and future air quality, both regionally and globally.
