Regional and global scale Modeling Unit

 

The evaluation of strategies to reduce mercury emissions, can be performed utilising global model simulations conducted under different scenarios of emission and reduction control. Such simulations allow cost/benefit ratios of potential measures to be estimated, and aid the choice of the most effective measures for future environmental policies.


The development and use of global models has contributed and still contributes to the improvement of knowledge regarding the physical and chemical mechanisms governing each phase of the mercury cycle. These models aid policy makers in verifying the achievement of global emission reduction targets, and to estimate the associated costs.


The "Regional and global scale Modeling” Unit aims to improve, validate and evaluate atmospheric models and models for the study of the global mercury cycle in order to support the Italian Ministry for the Environment Land and Sea, and other relevant bodies involved in the formulation of National Implementation Plans (NIPS), as described in the Minamata Convention. The Unit will also support UNEP in reviewing compliance with the reduction emission targets established by the Convention. The Unit will develop modules for the detailed representation of the fundamental mechanisms within the mercury cycle, with particular reference to the exchange of mercury and its compounds at air-water, air–soil and air-vegetation interfaces. Regional models will be developed for the evaluation of the impact of large industrial sites, as well as the study of areas characterized by sensitive ecosystems, such as the Arctic regions and the Mediterranean basin. Global models will be employed to assess possible changes in the mercury cycle in response to emission and climate changes.
