TFMM - TF HTAP Joint Workshop:
On Regional-Global and Air Quality-Climate Linkages
La Plaine Saint Denis, Paris, 17 to 19 June 2009
The TF HTAP will hold its next workshop in conjunction with the LRTAP Convention's Task Force on Measurements and Modeling in Paris , 17-19 June 2009. The meeting will be hosted by L'Institut National de l'Environnement Industriel et des Risques (INERIS) of the French Ministry of Ecology and Sustainable Development and will be held at La Plaine Saint Denis, Paris .
The joint workshop will begin on Wednesday afternoon, following the conclusion of the TFMM's annual meeting, which will take place 15-17 June 2009.
The joint workshop will be divided into 5 sessions exploring the following themes:
Methodological Issues in Linking Regional and Global Scale Air Quality Models
What methodological challenges have been encountered in linking regional and global scale models that may include different processes and have different structures and parameterizations? How have these challenges been addressed? How do the results of downscaling or one-way nesting compare to the results from multi-scale, two-way nested models? What lessons are available to be learned about the processes and resolution needed in models to quantify intercontinental transport?
The Impacts of Climate Change on Air Quality
How will the meteorological changes (including changes in temperature, precipitation, mixing heights, ...) expected from climate change affect air quality on regional and global scales? How will climate change affect synoptic transport patterns and the frequency of stagnation events? How will expected changes in global atmospheric composition affect air quality and long-range transport? How will climate change affect the magnitude of emission reductions needed to achieve air quality objectives?
The Impacts of Air Pollutants on Climate Change
How do traditional air pollutants, such as ozone and fine particle precursors, contribute to climate change? How do changes in the emissions of these pollutants on a regional scale affect climate on regional and global scales? What air pollution control strategies can have benefits for both air quality and climate change?
Discussion of Findings and Implications
This session will include summaries of the findings of the previous three technical sessions and a discussion of implications for the work plan of the TF HTAP, TF MM, and the LRTAP Convention. Main conclusions will be communicated to the negotiating body of the LRTAP Convention to inform the ongoing revision of the Gothenburg Protocol.
Status and Plans for HTAP Cooperative Work
This session will discuss the status of cooperative work under the TF HTAP including multi model experiments, emissions inventory improvements, and observational databases and analyses. We will discuss plans for contributions to HTAP 2010 and future efforts, focusing on how to bring the modeling, emissions, and observations work together to better inform our assessment.
The TFMM meeting (15-17 June) will include sessions discussing:
feedback from the EMEP field campaigns
the EMEP monitoring strategy
the revision of the EMEP strategy and the TFMM contribution
links with other EU or international initiatives (GAW, GMES, FAIRMODE, FP7 projects ...)
how to improve resolution over sensitive areas (urban, ecosystems...)
