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

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
Not complete chemical analysis of
measurements in Switzerland
 Model suggests that mineral dust
can be important in the summer
Measurements of organic carbon is much
higher than modeled, especially in winter
 Indications of problems with
official emission estimates
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 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
3
• 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

Intensive periodes 2012 and 2013
June 8 to July 12(7) 2012, and jan/febr 2013
One year measurements with ACSM (from june 2012)
High resolution, and extended measurements of aerosols
and its precursors (ACTRIS) while EMEP has a special focus
on mineral dust.

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: http://ebas.nilu.no/
 Future campaigns are not fixed. Potentially in 2016, though need partnerships
