GEMS/AIR (WHO) TWINNING INFORMATION
Note: EPA no longer updates this information, but it may be useful as a reference or resource.
The Global Environmental Monitoring System for Air Pollution (GEMS/AIR) is an urban air pollution monitoring and assessment program. Since its beginnings in 1973, GEMS/AIR has served to strengthen the capacity of participating countries in urban air quality management by providing training, monitoring equipment, quality assurance, and technical information exchange. The program, which has been jointly operated by the World Health Organization (WHO) and the United Nations Environment Programme (UNEP) since 1975, is a component of the UN Earthwatch system.
To help with this expansion in both numbers and types of air monitors, WHO/UNEP and USEPA have developed the Twinning Program. The idea of the Twinning Project is to match developed country programs and organizations with those in developing country programs. A developed country program can provide operational equipment and technical support to aid the developing country to join the GEMS/Air, improve its existing air monitoring program, and/or expand its monitoring capability to include additional pollutants.
