EMEP work-plan elements in 2007
2.2. Atmospheric measurements and modelling
Description/objectives:
To support the implementation of protocols to the
Convention; provide the measurement and modelling tools necessary for
further abatement policies; compile and evaluate information on transboundary
air pollution; and implement the EMEP monitoring strategy adopted in
2004. The Task Force on Measurements and Modelling, led by the United
Kingdom and co-chaired by WMO, reviews and assesses the scientific and
operational activities of EMEP related to monitoring and modelling,
evaluates their contribution to the effective implementation and further
development of the protocols, and reviews national activities related
to measurement, modelling and data validation.
Main activities and time schedule for monitoring:
(b) Review, store and make available the 2006
monitoring data (CCC, MSC-W, MSC-E); assess uncertainties relating to,
and the representativeness of, monitoring data on heavy metals and POPs
(CCC, MSC-E);
(k) Support the organization of a pilot study using passive and active
air samplers to monitor POPs across the EMEP domain in order to provide
spatially and temporally resolved air concentration data (CCC, MSC-E,
Parties);
(l) Evaluate the POP passive measurements campaign and compare with
modelling; evaluate the EMEP monitoring strategy in relation to the
outcome of this campaign as well as UNEP's global monitoring strategy;
report conclusions to the Task Force (MSC-E, CCC).
Main activities and time schedule for atmospheric modelling in general:
(c) Further develop the MSC-E models and report on
progress, taking into account the recommendations of the model review
(MSC-E);
(e) Complement EMEP data with data from other international programmes
and make a comprehensive comparison of observations with model results
(CCC, MSC-E, MSC-W, Parties).
Main activities and time schedule for atmospheric modelling for POPs
(a) Prepare information on polycyclic aromatic hydrocarbons
(PAHs) and toxic congeners of dioxins/furans (PCDD/Fs) for 2005: air
concentrations and depositions over Europe; comparison of modelling
results (concentration in air and precipitation, deposition fluxes)
with monitoring data; country-to-country matrices; estimates of depositions
on marginal seas (Mediterranean, Baltic, Black and North Seas); evaluation
of media response to a possible emission reduction scenario for PCDD/Fs
(MSC-E, CCC);
(b) Further develop the MSCE-POP model in accordance with the recommendations
of the model review: refine datasets of physical-chemical properties
used in modelling; develop the model parameterization for POP resuspension
and volatilization from soils and improve the model description of degradation
in the atmosphere and deposition processes and seasonal variations of
main processes (MSC-E);
(c) Prepare input data for the model application; use the ECMWF reanalysis
for the data preprocessing; prepare mapped emission data for regional
modelling based on both official and expert estimates (MSC-E);
(d) Complete stage III of the MSCE-POP model intercomparison study (comparison
of different model approaches to ranking a number of reference chemicals
with respect to longrange transport potential and overall persistence)
and the analysis of agreement and discrepancies between model simulations
of previous stages; cooperate with national experts on POP modelling
issues (MSC-E, Parties)
(e) Assess the atmospheric behaviour of possible new POPs;
(f) Investigate the possibility of applying inverse modelling for selected
POPs on the basis of measurement data, including passive sampling; (MSC-E).
2.4. Hemispheric transport of air pollution
Description/objectives:
Description/objectives: To develop a fuller scientific
understanding of the hemispheric transport of air pollution and estimate
the hemispheric transport of specific air pollutants, the Task Force
on the Hemispheric Transport of Air Pollution, led by the United States
and the European Community, coordinates activities, including collaboration
with other international bodies, programmes and networks, both within
and outside the UNECE region, with related interests.
Main activities and time schedule
(c) Continue the model intercomparison and evaluation
exercise and the development of intercomparison tools and information
infrastructure begun at Workshop on Intercontinental Transport Modelling
Intercomparison held on 30-31 January 2006 (Task Force; CCC, MSC-E,
MSC-W).

(b) Review, store and make available the 2005 monitoring data (CCC, MSC-W, MSC-E);
Main activities and time schedule for atmospheric modelling for POPs
(a) Prepare information using 2004 data to evaluate concentration and deposition fields of PAHs and toxic congeners of PCDD/Fs and to assess source-receptor relationships. Compare model results for concentrations in air and precipitation and deposition fluxes with measurements; analyse contributions from northern hemisphere sources to the European region and the contribution of European sources to other regions for PCBs, HCB, and g-HCH (MSC-E);
(b) Further develop the MSC-E model and its input databases of geophysical and meteorological data for regional and hemispherical modelling, paying special attention to POP transport in the marine environment at the hemispherical scale (MSC-E);
(c) Work on the third stage of the POP model intercomparison study; ranking a number of chemicals with respect to long-range transport potential and overall persistence (MSC-E, Parties);
(d) Work on evaluation of long-range transport potential and persistence of new substances (MSC-E).
2.4. Hemispheric transport of air pollution
Description/objectives:
To develop a fuller scientific understanding of the hemispheric transport of air pollution and estimate such transport for specific air pollutants. The Task Force on the Hemispheric Transport of Air Pollution, led by the United States and the European Community, will coordinate activities, including collaboration with other international bodies and networks with related interests within and outside the UNECE region.
Main activities and time schedule
(c) Link measurements at regional and hemispheric
scales; investigate further the intercontinental transport of air pollution
and assess its impact on European surface pollution levels, using the
EMEP monitoring data (CCC, MSC-E, MSC-W).
