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. Presentations are particularly encouraged with an assessment of the suitability of current observations and recommendations for stronger ones to constrain pollution vertical and long-range transport.
