Trade-offs between climate and air pollution policies


Specific Objectives:
1. To develop and test a global 3D-atmospheric chemistry transport model (TM5), with a 1x1 degree 2 way nested zoom capability, over the main polluted regions of Europe, Asia and North America. To set up a training facility with atmospheric models;
2. To develop regional and global inventories of atmospheric pollutant emissions from biomass burning for use in global and regional scale models, in collaboration with the IGAC-GEIA (Global Emission Inventory Activity) as well as other scientific partners (In collaboration with action GHG DATA);
3. To assess climate effect of ozone and aerosols in comparison with that of non-reactive greenhouse gases through a collaboration with the DG RTD sponsored project "Phoenics";
4. To integrate regional and global datasets on greenhouse gases, aerosol and ozone fields for use in integrated modelling exercises. To integrate ground-based and space-borne measurements of aerosols through the DG RTD funded GMES project "Create/Daedalus";
5. To create a common informatics system for easy integration and simultaneous use of the various datasets (e.g. emission inventories, concentration measurements from in-situ and remote sensing, meteorological data, model results) and to make them available as input to forward and inverse model calculations. Particular attention will be given to the consistency between regional and global scale datasets (in collaboration with action 2211 (Data Quality System of greenhouse gas emissions and sinks);
6. To perform high quality state-of-the-art aerosol measurements in the field to enhance data sets and to improve our knowledge on the formation, composition, radiative properties and removal of atmospheric aerosol. To develop a single particle mass spectrometer (SPASS) and various other measurement techniques ")(joint experiments with action 2112 (Air quality and Health);
7. To enhance the EMEP station into a super-station to understand interplay of ozone, aerosol and greenhouse gases. Contribution to European knowledge on the-state-of the atmosphere in the data-scarce Southern European region;
8. To benchmark smog chamber experiments for testing aerosol models that will be included in global climate models. To create a training facility in atmospheric chemistry;
9. To organise and facilitate discussions between researchers and policy makers about novel climate change mitigation techniques and to contribute to international assessments such as IPCC;
10. Studying the feasibility for setting up a research activity on "Systainability", based on the multidisciplinary expertise in the Global Change Priority and beyond Anticipated milestones and schedule The major milestones (and deadlines) are determined by the Committee meetings and Working Group meetings of DG ENV Monitoring Mechanisme Committee. For the rest, milestones coincide with the deliverables, as a more time resolved programming is not attempted.
Planned Deliverables:

1.1 Operational model, implemented on a local platform, tested for several aerosol and photochemical parameters;
2.1 Updated global emission inventory for the year 2000, utilising the Global Biomass Burning Initiative of the GVM unit;
2.1 Input to EDGAR/RIVM;
3.1 Aerosol dynamic model implemented in TM5 and the MPI Global Circulation Model ECHAM;
4.1 European PM phenomenology;
4.2 WMO-GAW version 2 aerosol-dataset;
4.3 Identification of ozone data in Mediterranean Area;
5.1 Definition of the informatic system for data/model integration;
6.1 Rhine Valley campaign and expanded data set on aerosols in Europe;
6.2 Software for analysing spectra from SPASS and calibration of SPASS;
7.1 One year of high quality continuous measurements of aerosol and gases and updated EMEP monitoring strategy;
8.1 New smog chamber and training facility in atmospheric chemistry;
9.1 Climate change-air pollution workshop;
10.1 Programme for annual summer school starting in 2004.
Summary of the Action:

This Action will collect, harmonise and integrate empirical data sets related to greenhouse gases and regional and global air pollution such as aerosols within a common framework. It will do so in collaboration with the World Meteorological Organisation's Global Atmosphere Watch, and UN-ECE's European Monitoring and Evaluation Programme (EMEP). The Action will use these data sets in conjunction with European and global scale atmospheric models and economic scenarios (Action 2213), in order to quantify the overall benefits of integrated versus sectoral policies. This Action will also actively look for consensus on scientific issues dealing with the interactions between climate change and air pollution, so as to allow the model calculations and assessments based on this science to be a firm basis for policy development. These goals will be achieved by strong networking with the scientific community (e.g contribution to the Intergovernmental Panel on Climate Change) and systematic contacts with policy makers. ERA objectives will be pursued through a few selected DG RTD Integrated Projects and Networks of Excellence. This action has built-in synergies with actions 2211 (Data Quality System for greenhouse gas emissions and sinks) 2213 (Energy and Industrial greenhouse gas emission scenario's) 2221 (Terrestrial ccosystem monitoring) 2222 (Advanced remote sensing methods) 2112 (Air quality and Health). Rationale The summary of the Intergovernmental Panel on Climate Change for policy makers (IPCC, 2001) states that, apart from greenhouse gases, conventional pollutants such as ozone and aerosols as well as land-use change have played a role in recent climate change. Therefore, they must also be considered to develop integrated climate change / air pollution policies for the long-term.
