Monitoring stations are intended to develop pollution transmissions estimates for transboundary policy and program use, including trends analysis, regional scale modeling and regulatory impact assessments.
Monitoring stations are necessary to develop and distribute technical guidance on emissions inventories for toxic air pollutants, including quality control/quality assurance and estimation procedures. Working in a transboundary context, monitoring stations should evaluate and develop new and revised emission factors to support inventory development and national regulatory efforts. Stations should conduct studies leading to the development of new or revised emission factors, including controlled and uncontrolled studies on criteria and toxic pollutant sources and species profiles. The monitoring centres will help develop new methodologies and techniques to estimate emissions from a variety of sources and provide leadership on the correct use of emissions inventories and factors methodology. The stations will provide leadership in the development and use of emission factors through; preparation and dissemination of technical guidance and information, and enhancements to and maintenance of reference guides and technical information dissemination tools.
