1. Future intensive field periods Recommendations
Wenche Aas
(EMEP/CCC)

2. Things to consider Scientific pressures Coverage Practical problems
Where are the main uncertainties and lack of knowledge
What to priority
Coverage
Need better spatial coverage in east of Europe (i.e. EECCA) for most components.
Vertical profiles to be better explored and coordinated
Practical problems
Cost
Need coordination with ongoing research projects

3. Scientific pressures (1)
Flux
Not typically EMEP work and dependent on research project
NitroEurope do N and C flux at several sites, but these are not usually EMEP sites, which often are not suited for this
Nitrogen partitioning (fine/course and gas/particle)
We did already include this in previous campaigns, but not with a high spatial resolution
It is expressed from several Parties a wish to evaluate the data we have before new campaigns on this topic
Photochemistry – VOC (biogenic especially)
It has been a focus on EC/OC, but not on the precursors
Previous intensive been in fall, winter and spring. A need for a summer campaign

4. Scientific pressures (2)
POPs: exchange between compartments (Soil, Sea, Air)
Need to include other measurement communities
Sites for the effect groups not necessarily collocated with EMEP
ICP IM sites may be an option
Expensive and demanding
POPs: spatial resolution –source identification
POP passive in EMEP 2006 being evaluated and new POP MONET/RECETOX being conducted (2009)
Active sampler needed –too difficult (cost & competence)
Heavy metal intensive for source identification
Daily and or hourly data needed
Cost issue

5. Recommendations
Intensive periods are important to support the EMEP program, and for capacity building
A need/wish for EU projects to get enough momentum (especially on flux, VOC, and POPs)
Need to evaluate the intensive periods we have accomplished before starting a similar
The most feasible things to include are maybe:
Heavy metals
BVOC –summer campaign
Summer 2010 the earliest. May wait until 2011 to ensure we have enough energy and interest in the community
