1. Assessment report website

• Informs about the objectives, organization and
  contributors to the Assessment Report
• Provides a tool for easy sending of national and
  regional contributions to the report via
  internet,
• Gives updated information about the progress and
  status of work,
• Provides a forum for comments and discussion
  among authors/ contributors
• Initiated on May 2002, regularly updated
• http//www.emep.int

2. Trajectories to EMEP network

• 2D trajectories to operative EMEP stations
• Backwards trajectories (96h long, 6-hourly
  output)
• Daily sector values
• Trajectory crossing maps
• 2D trajectories from 1985-1996 have been
  available since January 2002
• 2D trajectories from 1997-2000 are now available
  in 50x50 km2
• Backwards trajectories (New format file)
• Daily sector values (Extended file)
• Trajectory crossing maps (New maps, choice from
  Parties)
• http//webdab.emep.int

3. WebDab with emission data

• Initiated on June 2002, first update on October
  2002
• Official emission data submitted to UNECE/EMEP by
  the Parties to the LRTAP Convention
• National Totals (1980-2000, projections for
  2010)
• National Sector Totals (1980-2000, projections
  2010)
• Expert estimates for acidification,
  eutrophication and ground level ozone
• Gap filling for national totals (1980-2000,
  projections for 2010)
• Gridded emission totals (Base 2002, scaled
  for all reported years)
• Gridded sector data (Base 2002, scaled for
  all reported years)
• http//webdab.emep.int

4. Lagrangian model calculations

• Daily concentrations in air and in precipitation
  from 1985 to 1996 at operative EMEP stations
• Available since March 2001
• Documented emission data used in the Lagrangian
  model calculations/scaling
• Available since November 2002
• http//webdab.emep.int

5. Eulerian model calculations

• Contribution to Part 1 of the Assessment report

These results are part of the evaluation process
of the Unified EMEP model

The importance of vertical distribution of
emissions

• Data provided by Sonja Vidic (Sept. 2002)
• Study of the effective height of emissions from 7
  power plants and 1 industrial plant in Zagreb
  (Croatia)
• Physical height of plants 60m, 150m, 200m
• Meteorological conditions from 1997-2001,
• Study of plant emission dispersion in monthly
  basis (Briggs formula)
• Parameterised to typical height of 150m in EMEP
  model, same annual variation for all countries
  Need for actual data from Parties

• EMEP model parametrisation allocated percent of
  emissions to different mndel heigths
