Atmospheric Composition and Dynamics

The role of dynamics in atmospheric composition is a recent research line of our group. This includes investigating the effect that synoptic scale weather systems exert on the surface concentrations of air pollutants such as ozone (O3) and particulate matter (PM). We use observations of atmospheric constituents, meteorological reanalysis data and objective classification methods (see Tropospheric Climate Variability and Change research line) to establish links between atmospheric composition and circulation. We also apply clustering algorithms and complex machine-learning techniques to understand the weather regimes which trigger extreme air pollution episodes.
