A Parallel Framework for the Simulation of Emission, Transport, Transformation and Deposition of Atmospheric Mercury on a Regional Scale

摘要

The cycle involving emission, atmospheric transport, chemical transformation and deposition, is often a major source of mercury contamination in places distant from anthropogenic sources. Therefore atmospheric modelling and simulation are important to evaluate the association between emissions and potential effects on human health. Unfortunately, once released into the atmosphere, mercury is subjected to a variety of complex physical-chemical processes before its deposition. Thus performing detailed mercury-cycle simulations on the large spatial scale required implies the use of parallel computing. In this work, chemistry, photolysis, emissions and deposition models have been linked to open-source atmospheric meteorological / dispersion software. The result is a parallel modelling system, capable of long term simulations and mercury emission reduction scenario analyses.
