Atmospheric convection and its impacts on chemical tracer distribution and transport present a significant challenge to modeling of both climate and atmospheric composition. The global and regional impacts of convection on clouds, water vapor and trace gases are large and poorly quantified especially in the upper troposphere, leading to significant uncertainties in radiative forcing and in the impact on global air quality. The goal of this proposed session is to solicit recent global observations from satellite and their applications for improving model simulations of convective transport and associated atmospheric composition. We encourage abstract submissions to the following topics: Topic 1: Modeling of convection in global, regional, and process level models Topic 2: Modeling convective influence on atmospheric composition in global and regional chemistry models Topic 3: Using satellite observations to diagnosis convective influence on global and regional atmospheric composition.
