Berlin, June 10-11, 2002

EMEP activities and challenges of relevance for effect oriented activities
the emep vision
To be the main science based and policy-driven instrument for international cooperation in atmospheric monitoring and modelling activities, emission inventories and projections, and integrated assessment to help solve transboundary air pollution problems in EuropeThe EMEP vision;
slide3
Science – EMEP establishes sound scientific evidence to underpin, develop and evaluate environmental policies

Partnership – EMEP fosters international partnership to find solutions to environmental problems

Openness – EMEP encourages the open use of intellectual resources and products

Sharing – EMEP is transparent and shares information

Organization – EMEP is organized to integrate information on emissions, environmental quality, effects and abatement options

EMEP-CCC tasks

  • Recommendation of methods, preparation of manuals,
  • Field and laboratory intercomparisons,
  • Data and metadata collection, validation and storage,
  • Evaluate QA/QC-procedures
  • Data interpretation,
    • data reports and joint reports
    • comparison with CTM-estimates
    • deposition and exposure estimates
  • Representativeness
  • Development of network and measurement programme,
  • Coordinates the EMEP work on particulate matter (PM) MSC-W; acid, eutroph, ox, (emissions and modelling)
      • MSC-E; HM and POPs (emissions and modelling)
      • CIAM; Integrated assessment modelling

developments of relevance
The new EMEP CTM (the unified model)

Improved deposition scheme (surface specific dry dep)

Flux based (ozone)(workshop June 2002)

Improved spatial resolution (50x50 km2)

The EMEP Assessment work

Revision of the monitoring strategy

Harmonisation of methods

Cooperation, (network integration)

Deposition of base cations

Historical emission data

Developments of relevance
slide15

The EMEP assessment report;

An assessment report is being prepared where national experts and the EMEP centres are reviewing the information generated since the programme was initiated in the late 1970ies.

The report will contain both national/regional evaluations as well as have an overall European perspective, and is to be completed in 2003 (will provide input to the WGE substantive report).

This work will be based on information available on observations, model calculations of concentrations and depositions and flux calculation between countries. It will aim at evaluating trends in sulphur, nitrogen, ozone, heavy metals and POPs and discuss emission changes (including the influence of legislation), changes in climatology (meteorology or changes in surface characteristics) and data quality

slide16

Comparing 1980-82 vs. 1995-97

Deposition

Exceedance

challenges for the measurement and modelling activities
Improved spatial and temporal resolution

Linking of scales (regional – local)(health aspects is the driving force)

Site specific deposition and exposure estimates

Site density,

dry deposition monitoring, uptake modelling,

other methods (e.g. Throughfall; ICP F, Expert Panel on Deposition)

Importance of hemispheric transport

Geographical coverage of observations

New technologies

Remote sensing

Data assimilation

Particulate matter

Basecations

Challenges for the measurement and modelling activities
review of the emep monitoring strategy
The TFMM will review the EMEP monitoring strategy

A strategy for particultate matter has been adopted and is currently under implementation

A concept for the new strategy has been outlined considering

Current status

Shortcomings

Need for more strict monitoring obligations

New requirements

New developments

Need for conservatism

Review of the EMEP monitoring strategy
purpose of the monitoring programme
Spatial characterisation of atmospheric composition and deposition amounts

Regional features

Detailed and site specific

Temporal changes

In relation to emission changes

compliance

natural variations

CTM validation

Understanding processes

Model development

Non-linearities

Purpose of the monitoring programme
particular needs
Long term data provision

Provide a formal basis for monitoring

Adequate and known quality

Siting

Methodology

Training

Quality assurance

Data availability

Expert involvement and scientific credibility

Consider financial limitations

Particular needs
slide22
A ”level” approach is proposed

Open for the use of other relevant data

Encourage national efforts

Level 1; Mandatory programme, large number of sites

Spatial and temporal trends

Continuous sampling

Level 2; Advanced measurements at selected sites

Expensive or technically demanding

Spatial and temporal trends

Process oriented

Continuous or campaigns

Level 3; Research data

Expensive or technically demanding

Process oriented

Campaigns or continuous

slide23
Level 2 and level 3 sites could be nominated as ”EMEP supersites”

Important motivation factor

Provides recognition for the data providers

Countries themselves are responsible for nomination of sites

Supersites could be topic specific (important overlaps)

acidification/eutrofication

fotooxidants

heavy metals

persistent organic compounds

particles

provide complementary data to the extent possible

Monitoring required for the individual topics need revision

Parameters, Time resolution, Spatial coverage, Methodologies

Priorities between topics should be also revised

Assessment report will give guidance

slide24
Distribution of Level 2 and level 3 sites

Geographic consideration with respect to topic

National involvement and interests

Cost limitations/cost sharing

Still need for monitoring campaigns

Denuder campaigns

EC/OC campaigns

VOC campaigns

.......

flux measurements
Applicable methods have previously not been available

Improved micrometeorological methods have recently been developed (e.g. Eurotrac BIATEX2)

Relaxed eddy accumulation method

Ozone uptake modelling

Improved dry deposition scheme in EMEP model

Speulder forest; From Erisman et al,

what can we obtain from low cost methods like passive flux samplers and diffusion denuders
Site representativity

Improved spatial resolution, the UK example

Trend studies (non-linearities)
