Atmospheric Chemical Transport Modelling and application to simulate air pollution and effects on natural ecosystems
Atmospheric Chemical Transport Models (ACTMs) simulate the emissions, transport, chemical transformation in the atmosphere and deposition to the surface of air pollutants at national and regional scales. They have the ability to generate spatially distributed information on different pollutants including acid, nitrate and heavy metal deposition as well as surface concentrations of ozone and particulate matter. Such pollutants are known to pose a threat to both natural ecosystems and biodiversity as well as human health.
The advantages of using ACTMs include: their ability to simulate the concentration and deposition of pollutants at a large number of model grid points; source attribution capabilities, such as identifying the relative contribution of individual emission source or countries to levels of pollution; predictive abilities such as simulating future changes in air pollution based on projected emissions changes. Multiple model simulations can be applied to both uncertainty assessment and to integrated assessment modelling which is used to calculate the most cost effective pollution abatement strategy to protect human health and the natural environment.
A number of different examples of the simulation of the concentration and deposition of pollutants are presented, focusing on regional scale applications of acid and nitrogen deposition over the UK and Poland.
