  2. COLLABORATING INSTITUTIONS • Dept. Environmental Science & Technology, Imperial College London • Integration and Abatement Strategy modelling • Centre for Ecology & Hydrology (CEH), Edinburgh Research Station • Atmospheric Transport & Deposition • CEH, Monks Wood, Cambridgeshire • Ecosystem Critical Loads & Exceedances • CEH, Wallingford, Oxfordshire • ANC & Target Loads Functions for freshwaters • Entec UK Ltd • Emissions Data & Cost-curve generation TFIAM, Haarlem, The Netherlands, 7-9 May 2003

  3. TFIAM, Haarlem, The Netherlands, 7-9 May 2003

  4. SPATIAL RESOLUTION TFIAM, Haarlem, The Netherlands, 7-9 May 2003

  5. TFIAM, Haarlem, The Netherlands, 7-9 May 2003

  6. OPTIMISATION PROCESSING TFIAM, Haarlem, The Netherlands, 7-9 May 2003

  7. OPTIMISATION MODES • Deposition • Direct effect of abatement measures • Accumulated Exceedance • Indirect effect of abatement; ecosystem specific • Human Exposure • Primary & secondary particulates (PM10); ecosystem independent • Acid Neutralising Capacity • Target Load Functions; freshwater only TFIAM, Haarlem, The Netherlands, 7-9 May 2003

  8. MODEL OUTPUTS(Examples) TFIAM, Haarlem, The Netherlands, 7-9 May 2003

  9. Deposition Maps TFIAM, Haarlem, The Netherlands, 7-9 May 2003

  10. Exceedance Maps TFIAM, Haarlem, The Netherlands, 7-9 May 2003

  11. Individual abatement measures TFIAM, Haarlem, The Netherlands, 7-9 May 2003

  12. TFIAM, Haarlem, The Netherlands, 7-9 May 2003

  13. DEVELOPMENT STATUS(Summary) • Combined ‘scenario’ and ‘optimisation’ modes • Area, point & national sources recognised • SOx, NOx, NH3 and primary & secondary PM10 • Sector specific emissions/cost-curves • Acidification, eutrophication & exposure optimisation • ANC Target Load Functions incorporated • User-specified weightings for scenario definition • Generic design facilitates nesting of models TFIAM, Haarlem, The Netherlands, 7-9 May 2003

  14. NEW DATASET AVAILABILITY • Emissions & Cost-curves (May 2003) – Entec UK • Deposition Data (Summer 2003) – CEH Edinburgh • Critical Loads (Summer 2003) – CEH Monks Wood • Ammonia Cost-curves (Year End 2003) – NARSES TFIAM, Haarlem, The Netherlands, 7-9 May 2003

  15. ONGOING DEVELOPMENT • Dynamic Modelling (ANC Target Load Functions) • Incorporation of in-square NH3 deposition dynamics • Implementation of Critical Loads FUTURE DEVELOPMENT: • Dynamic Cost-curves (multi-pollutant & delay time) • Incorporation of SSSI’s into optimisation processing • Incorporation of VOC’s and Ozone TFIAM, Haarlem, The Netherlands, 7-9 May 2003
