1. 2005 20062007 5-year analysis Upgrade + integration Direct model implementation BB sources Soil dust 1D-VAR /4D-VARadjointization analysis Evaluation

2. WORK PLAN WP1: Implementation of the direct model - implement present versionLOA/MPI/ECMWF - BB sources and injection heightFMI/MPI - emissions of dust soilNMO/MPI WP2: Data assimilationLOA/ECMWF/Köln - adjointization of RT codes - Preparation of satellite data - 1D-VAR implementation - 4D-VAR implementation WP3: Production of a 5-yr analysisECMWF

3. WORK PLAN (continued) WP4: Evaluation and analysis - surface radiationECMWF/LOA/KMI - AODECMWF/KMI/LOA - aerosol fieldsGalway (chemistry and physics) - analysis of source contribution + System upgrade from WP1 after 2 years & Integration with other sub-projects in 2007 + Overall evaluation

4. CROSS-CUTTING THEMES Interface with RG Interface with AQ (global / regional) Biomass burning emissions (RG, GG) Biogenic emissions (RG) Code development (advection, convection, diffusion)

5. Interface AQ/AEROSOL - boundary conditions (lateral, top) - expertise on data assiilation (surface vs satellite) - feedback from AQ models/groups on AEROSOL model - high-resolution emissions over EMEP region SO 2, VOC, NH 3, PM2.5, PM10, 50x50 km² + hourly,weekly,monthly - link to ACCENT to consolidate emission - long range transport of dust

6. DELIVERABLES - INTERIM * - FINAL * 4D distribution of atmospheric aerosols at 50-100 km resolution * aerosol properties for all sorts of atmospheric corrections * concentrations of PM for air pollution related issues * initial and boundary conditions for smaller-scale air quality models * visibility range (e.g., air traffic, tourism) 2 * photosynthetically active radiation (for e.g. CO 2 cycle) * aerosol deposition flux (impact on vegetation, acid rain) - IN (what we need!) *
