EMEP intensive measurement periods To assist the implementation of the EMEP monitoring strategy. The task force of measurement and modelling (TFMM) has recommended conducting co-ordinated intensive measurements between the Level-2 sites (joint EMEP/GAW supersites). Furthermore, cooperation and involvement of research groups with more advanced research activities (i.e. level 3) has been encouraged 2nd Period  17 Sep – 16 Oct 2008  25 Feb – 26 Mar rd Period  8 to July 12(17) 2012  11 jan - 8 Febr st Period  of June 2006  8 Jan -4 Feb 2007 Outline of this talk Some main results from the different measurement periods  highlight the interlink with research projects  Highlight the importance of infrastructure project to develop harmonized methodology and reporting guidelines in Europe

Intensive measurements 2006/2007

Data available from 2006/2007

Chemical speciation comparison Measurements of organic carbon is much higher than modeled, especially in winter Indications of problems with official emission estimates Not complete chemical analysis of measurements in Switzerland Model suggests that mineral dust can be important in the summer

Lessons learnt from the 1. EMEP IMP Produced a set of valuable data and new possibilities for validation of the EMEP model, In particular: size-distribution and formation rates of HNO 3 and coarse nitrate the diurnal variation of ammonia, EMEP model to be coupled to a dynamic ammonia emission module underestimation of EC and OC at southern sites, suggesting that residential wood burning source is underestimated in winter Identified several measurement problems Lack of mineral dust measurements Biased measurements for nitrogen and carbonaceous matter Lack of comparability No standardized reporting format Improved in future intensive periods

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 Monitoring frameworks: Infrastructure projects

Summary  The EMEP intensive measurement periods have become an important part of the monitoring programme  Production of high resolution and/or advanced measurement (EUCAARI and ACTRIS).  Production of chemical composition data on mineral dust and carbonaceous matter using comparable field and analytical methodology at a number of regional background sites representative of different European regions  Established reporting guidelines and QA/QC procedures for a range of new components for the EMEP Community (EUSAAR and ACTRIS project central)  Enhanced the cooperation between the research and monitoring communities – win win, co benefit:  EMEP benefits from the scientific development and development of reference methods and reporting  Research projects benefits from infrastructure and added value of the data (increased visibility). Partnership is often a prerequisite to get funding from the Commission  Data available at:  Future campaigns are not fixed. Potentially in 2016, though need partnerships
