OPTIMISATION PROCESSING
![Page 7: UK Integrated Assessment Model (UKIAM)](https://reader035.vdocument.in/reader035/viewer/2022062801/5681431e550346895daf811e/html5/thumbnails/7.jpg)
TFIAM, Haarlem, The Netherlands, 7-9 May 2003
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

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

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
