  1. EUCAARI European Integrated Project on Aerosol - Climate - Air Quality Interactions

  2. Background of EUCAARI • Estimates on climate effect of aerosols have large uncertainity • Physical, dynamical parameterizations do not give consistent results to climate forcing • Future climate effect to parameterizations done for current climate are often poorly known • What will be the natural sources of aerosols in changing climate? • Current and future and controls of anthropogenic primary aerosol and precursor emissions • Do they have a feedback to climate?

  3. Objectives of EUCAARI 1.Reduction of the current uncertainty of the impact of aerosol particles on climate by 50% and quantification of the relationship between anthropogenic aerosol particles and regional air quality. To achieve this objective EUCAARI will concentrate on the areas of greatest uncertainties and will: • Identify and quantify the processes and sources governing global and regional aerosol concentrations • Quantify the physico-chemical properties of atmospheric aerosols • Quantify the feedback processes that link climate change and atmospheric aerosol concentrations with emphasis on the production and loading of natural aerosols and their precursors 2. Quantification of the side effects of European air quality directives on global and regional climate, and provide tools for future quantifications for different stakeholders. 1a 1b 2 1c

  5. Organization of Work • The project is divided to elements which coordinate studies of different parts of aerosol life-cycle • Cross-disiplinarity • Multi-scale and –method approach • Each Element has Work Packages, which in turn are divided into Tasks

  6. Organization

  7. WP3.2, i.e. us! Management PROJECT OFFICE ELEMENT LEADERS WORK PACKAGES Work Packages describe a single problem or methodology. Each WP has one or more Milestones to deliver. They are subdivided into tasks with different Deliverables Element managers lead the Elements and provide information of element progress and results to other elements and to Project coordination Project office handles the day-to-day project wide coordination, IP issues and reporting

  8. Project Timelime • Project is organized in phases • Experiments and infrastructure building are concentrated on start of the project • Global climate and policy modelling in the end of the project WP3.2 involvement
