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. In the context of the changing climate and rising global pollution level it is important to improve our understanding of the main mechanisms which control long- and mid-term variability of the key tropospheric species, and particularly the greenhouse gases. 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 controlling the changes of the tropospheric chemical composition. We invite contributions on new analyses including climatological assessments of long-term data sets of tropospheric ozone and its precursors, greenhouse gases. Contributions on the new comparisons of existing in-situ measurements data with new satellite data products for troposphere are appreciated. Of the interest the multi-annual models simulations with different emission scenario both of the past and future. The results obtained in the frames of national and international which contributes to a better understanding of the atmospheric composition variability and trends are particularly welcome. However, we explicitly encourage other contributions relevant to the session topic. The session is partly supported by ACCENT T&TP sub-project.
