  1. GEMS AEROSOL WP2 refinement of aerosol emission sources M.Sofiev Air Quality Research Finnish Meteorological Institute

  2. Task 2.1 Update and assimilation of the anthropogenic emission inventories of aerosol and its precursors. Task 2.2. Assimilation of information on the wild fires Task 2.3. Quantification of the wind-blown dust emission from desert areas Task 2.4. Quantification of the wind-blown sea salt emission Task 2.5. Sources of stratospheric aerosols Tasks of WP2 (emission)

  3. GEIA / ACCENT / RETRO / EMEP Emission data AER_2.1 data bases RAQ Emission data AER_2.2 wild fires GRG Methodology, data Fire counts AER_2.3 dust emis. AER_3 Data assimilation ESA EUMETSAT NASA Data, modules AER_2.4 sea salt emis SO2 data Global aerosol monitoring system AER_2.5 stratosph. Information flows in AER WP2

  5. An overview of the existing emission inventories (FMI, HALO paper) 10 official and scientific inventories nearly all needed species are covered strongly varying coverage and resolution, overlaps and differences between the methodologies and reference periods necessity to have a mapping of the databases to the best-represented regions and species During the kick-off the emission task force is going to meet and agree upon a harmonised approach Task 2.1: anthropogenic emission

  6. Two sources of information: fire counts (suitable for NRT applications) and burnt areas (past analysis) An inventory of fire-count products has been made (HALO paper) there are several near-real-time products available fire counts tend to strongly under-estimate the fire area, which might require recalibration of more sophisticated improvements Modification for transforming GWEM (emission composition and total mass) to a NRT instrument and its linking with BUOYANT model (plume elevation) are being considered Task 2.2: wild fires

  7. Basic schemes: Balkanski et al., Tegen et al. ORCHIDEE vegetation dynamic model for dynamic land characteristics Task 2.3 wind-blown dust

  8. Consideration of wide size spectrum of particles is needed Several schemes are available (Monahan, Smith&Harrison, Andreas), as well as their intercomparison Task 2.4 sea-salt emission

  9. Task 2.4 sea-salt emission (2)

  10. Main stratospheric source is: volcanic SO2 from eruptions Other sources are primarily tropospheric and thus will be treated via troposphere-stratosphere exchange Main method for SO2 from volcanoes: data assimilation (after 18 month of the project) Task 2.5stratospheric sulphates

  11. Discuss and implement anthropogenic emission database – in a harmonized manner with other sub-projects Develop a scheme of wild fires accounting from hot-spot satellite products and start testing and calibration of the model Start implementation of existing schemes for wind-blown dust and sea-salt emissions First-step tasks
