  Information - AS3.04 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. This year we particularly welcome contributions showing
initial results from the field campaigns in Europe and North America
during summer 2004 within the framework of ICARTT (International
Consortium for Atmospheric Research on Transport and Transformation).
