Canadian Global Emissions Interpretation Centre, Canadian ORTECH Environmental Inc.
Data Center Description
The Canadian Global Emissions Interpretation Centre (CGEIC), has been established by Environment Canada jointly with Canadian ORTECH Environmental in order to serve both the national and international scientific and policy-making communities. The primary purpose of CGEIC is to provide emissions inventory input for a variety of modelling activities.
CGEIC is a comprehensive emissions inventory service, available to the scientific, industrial and policy-making communities. The primary purpose of the Centre is to provide input data for mathematical models, such as those being used to link sources to receptors, and to evaluate strategies to minimize the impact of atmospheric pollutants. Canada is concerned about a variety of atmospheric issues, including global warming, acid deposition, tropospheric ozone and air toxics, all of which require emission inventory data for input into urban, regional and global scale models. In the case of air toxics, there is considerable evidence that persistent organic pollutants (POPs) and heavy metals (HMs) circulate globally and accumulate in areas extending from the Great Lakes Basin to the Canadian High Arctic. Establishing the sources of pollutants and their emissions are first steps towards reducing their levels in the environment. The analysis of emission trends is also important in developing ways to manage such chemicals more effectively.
The preparation of global emissions inventories for models and other applications requires international cooperation in the exchange of data. In some instances, the assembly, quality assurance and processing of this information can take many months, or even years. One of the missions of CGEIC is to greatly shorten the period between the identification of the need for specific emissions data and their delivery.
