Chemical Coordinating Centre (CCC) is hosted by the Norwegian Institute for Air Research (NILU). The main tasks of the CCC are co-ordination and intercalibration of chemical air quality and precipitation measurements carried out on the basis of EMEP measurement programme. The measurement programme includes recommendations of methods to be employed in the countries in their monitoring, quality assurance and training (including field and laboratory intercomparisons), data validation and reporting as well as data storage. Besides the CCC leads the EMEP work in the field of atmospheric particulate matter.
The EMEP Centre on Emission Inventories and Projections (CEIP) is hosted by the Umweltbundesamt Vienna (UBA-V) Austria. The main task of the CEIP is to collect emissions and projections from Parties to the LRTAP Convention, and to prepare data sets as input for long-range transport models. The emission centre has also been assigned the task of reviewing the submitted emissions to assist the Parties improving the quality of national inventories.
The EMEP Centre on Integrated Assessment Modelling (CIAM) is hosted by International Institute for Applied Systems Analysis (IIASA). The CIAM prepares technical background material for the annual meetings of the Task Force on Integrated Assessment Modelling (TFIAM). The Task Force brings together information gathered from the Parties and from other Convention bodies on cost-effective emission control strategies. Its regular reports to the negotiating bodies of the Convention assist in the development of legal instruments (protocols).
The Meteorological Synthesizing Centre-East (MSC-E) of EMEP is located in Moscow, Russia. The main task of the centre is to model transboundary fluxes and source-receptor relationships of heavy metals and persistent organic pollutants.
The Meteorological Sinthesizing Centre West (MSC-W) of EMEP is hosted by the Norwegian Meteorological Institute (DNMI). The main task of the centre is to model transboundary fluxes and source-receptor relationships of acidifying and eutrophying air pollution, photochemical oxidants and particulate matter.
