  Information - AS3.05 Vertical and Long-Range Transport of Trace Gases and Aerosols

Event Information
Vertical and long-range transport of trace gases and aerosols are key factors controlling their concentrations and variability. Surface emissions have a strong direct influence on the upper troposphere via several vertical transport processes, especially cumulus convection
and lifting associated with frontal systems (warm and cold conveyor belts). Downward transport occurs via accompanying subsidence, while precipitation scavenging is one of the key sinks for many gases and aerosols. Long-range and intercontinental transport result in measurable enhancements of gas and aerosol concentrations in populated and agricultural regions due to industrial and biomass burning
emissions thousands of kilometers upstream. Even many "remote" marine regions are far from being free from the direct influence of relatively short-lived gases and aerosols produced over far away continents. Numerous tools have been applied to studying transport-related issues, including observations (long-term, campaign, and satellite) and models (cloud-scale to global). We invite talks covering all aspects of this topic, and especially encourage those
which synergistically combine various types of models and
observations. During the International Polar Year, we particularly welcome contributions studying transport of pollution to the polar regions. We also especially invite contributions resulting from the Tropical Composition, Cloud and Climate Coupling (TC4) study, as well as related activities.
