  2. User requirements

  3. Committed end users • European Environmental Agency (EEA) • University of Edinburgh • Min. of Environmental Protection of China (MEP) • Indian Inst. of Tropical Meteorology (IITM) • South African Weather service (SAWS) • National institute for Env. Studies Japan (NIES) Specific user requirements: • Species: NOx, CH4, CO, NMVOC, SO2, PM, O3 • Accuracy: better than 30% - 80 % • Spatial resolution: 1 km - 50 km • Time resolution: daily – annual

  4. User Requirements: Regions

  5. User Requirements: Temporal/Spatial

  6. Do the bottom-up inventories match the user requirements ? • Species : • Number of species is more than enough • Accuracy: • Usual sufficient • Some regions are unreliable • Spatial: • Sometimes a higher resolution is requested • Africa is under-represented in the regional inventories • Temporal: • More recent emission estimates needed • Higher temporal resolution needed: monthly or daily

  7. Can GlobEmission using satellite observations improve this ? • Species : • Focus on a few targetted species (–) • Accuracy: • Probably sufficient, but it still has to prove itself (±) • All regions are treated similar (+) • Spatial: • Sometimes a higher resolution is requested (±) • Regional inventory dedicated to South-Africa (+) • Temporal: • Emission estimates will be made available almost immediately (++) • Monthly temporal resolution possible (+)

  8. Project Overview

  9. GlobEmission: Approach • Based on satellite observations using inversion techniques • Complementary to bottom-up inventories (not replacing) • Focus on a limited number of species: • NOx, CH4, CO, NMVOC, SO2, PM • Validation with existing inventories and model results • Goal: to demonstrate the validity of the concept

  10. Service implementation Dedicated services for the following four types of emission estimates: • Global • Inversion of HCHO, CHOCHO on a global domain • CO inventory assessment • Regional • NO2 (and O3) and SO2 over South Africa, China, India (high resolution) 2b. High resolution Emission Maps • Spatial disaggregation to create high resolution maps over South Africa • European • Inversion of NOx in Europe • Verification of SO2 and CO inventories in Europe (and O3) • Aerosol-related • Aerosol inversion over Europe, South Africa, China and Japan • Forest Fire emissions

  11. Global Emission Estimates Service provider : BIRA-IASB Main users: NIES, Univ. Edinburgh Main tasks: • Inversion of HCHO, CHOCHO on a global domain • Derivation of global NMVOC emissions constrained by HCHO retrievals. • Derivation of global natural emissions of isoprene using HCHO column data. • Derivation of the missing biogenic source of CHOCHO over land using combined HCHO and CHOCHO retrievals. • Evaluation and improvement of the anthropogenic CO emission inventories.

  12. Regional Emission Estimates Service provider : KNMI Main users: SAWS (South Africa), IITM (India), MEP (China) Main tasks : • Derivation of NO2 (and O3) and SO2 emissios using CHIMERE and UV-VIS satellite data • On a 25×25 km2 resolution over China, India and South Africa

  13. Service provider : VITO Main users: SAWS (South Africa) Main tasks : The E-MAP tool is used to grid air pollutants (e.g. NOx, SO2, PM10) as input to air quality models for different regions and at different resolutions. This tool will be extended towards South Africa as to allow spatial disaggregation of (low-resolution) regional emission inventories for South Africa derived from satellite observations to high-resolution regional inventories High resolution emission inventories for the “Regional Emission Estimates” of South Africa Left: NOx point source emissions stemming from industrial production processes (SNAP 4) Right: NOx traffic emissions (SNAP 7) disaggregated on a 5x5 km² grid.

  14. European Emissions Estimates Service provider : TNO and KNMI Main users: EEA Main tasks: • Derivation of sectoral emission estimates for NOx, SO2 and CO for the years 2009-2010 per country and per year, using LOTOS-EUROS model and satellite data. • Investigating the effect of a new NOx emission inventory on ozone formation • Verication of existing EMEP NOx, SO2 and CO emission inventories.

  15. FMI: Emission estimates related to aerosols Service provider : FMI Main users: MEP, SAWS, NIES, Univ. Edinburgh, EEA Main tasks: • Aerosol inversion over Europe, South Africa, China and Japan using SILAM and satellite data • Deriving Forest Fire emissions
