Tasks of the EMEP Chemical Coordinating Centre
• Develop and coordinate the observation activities required to assess air pollution across the EMEP geographical domain
• Secure and improve quality and representativeness of observations• Quality assurance and quality control of data submitted by Parties• Archival and dissemination of observation data and associated
meta-data.• Assessment of data and provide information to stakeholders about
results from monitoring activities• Serve the interest of EMEP monitoring activities with respect to
relevant activities under other frameworks to ensure harmonization, efficient use of resources and multiple usage of data.
Particulate matter/aerosols, Oxidants and precursors, Eutrophication, Acidification, Heavy metals, Persistent Organic Pollutants, Short-lived climate pollutants, tracers, (greenhouse gases)

Data quality and quality control• Essential to have harmonized measurements to be able to do
comparison over time and space• Standard operation procedures and reference methods developed• Regular field and laboratory intercomparison• Reporting guidlines, incl metadata info etc
Monitoring frameworks:
Infrastructure projects

Historical development
![Page 10: Developments in EMEP monitoring strategy and recommendations from AirMonTech](https://reader035.fdocuments.us/reader035/viewer/2022062816/56816393550346895dd489c1/html5/thumbnails/10.jpg)
One example of trends: SulphurResults from the EMEP monitoring show 70-90% reductions in ambient concentrations and deposition of sulphur species since 1980. Despite these significant reductions, sulphate still remains one of the single most important compounds contributing to regional scale aerosol mass concentration.

EMEP Monitoring programme:Level 1• Main ions in precipitation and in air • heavy metals in precipitations• ozone • gas particle nitrogen ratios (low cost)• PM10 and PM2.5 mass • meteorology at ca 125 sites
Level 2, supersite (joint EMEP/GAW)• PM composition (EC/OC, mineral dust)• Aerosol physical and optical properties• CH4• Tracers (CO and halocarbons)• POPs• Heavy metals in air and aerosols• VOC+ all level 1 activities20-30 sites
Both levels are mandatory

Point maps may be the best way to show level 2 data available.

EMEP level 3• Research based and voluntary
monitoring• Includes campaign data• Contribute to understand atmospheric
processes and transport of air pollutants• E.g: flux measurements, NOy, vertical
profiles, isotopes, H2, Hg speciation WSOC etc etc

EMEP intensive measurement periodsTo assist the implementation of the monitoring strategy, TFMM has recommended conducting co-ordinated intensive measurements between the Level-2 sites. Furthermore, cooperation and involvement of research groups with more advanced research activities (i.e level 3) has been encouraged
