  Information - AS3.04 Tropospheric Composition: Variability and Trends

Event Information
This session focuses on the variability of the tropospheric chemical composition on seasonal to decadal timescales. Understanding of the main mechanisms driving the seasonal and interannual variability of tropospheric air pollutants and greenhouse gases is an essential aspect for climate change studies and can have important implications for future pollution control measures. Long-term monitoring data at surface sites, vertical soundings, and satellite data, and multi-annual model simulations on the global or regional scale can help to understand the role of anthropogenic and natural factors in controling the changes of the tropospheric chemical composition. We invite contributions on new analyses of long-term data sets of tropospheric ozone and its precursors, greenhouse gases, and aerosol compounds, and on multi-annual emission data sets and model simulations of the past and future. Several national, European, and
international programmes have contributed to a better understanding of the atmospheric composition variability and trends, and contributions from these projects (e.g. RETRO, TOR, TROTREP, ACCENT, QUANTIFY, EVERGREEN) are particularly welcome. This year, a special focus will be placed on results from the RETRO project, which will terminate in summer 2006. However, we explicitly encourage other contributions relevant to the session topic.
