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 Meteorologisk Institutt met.no

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 Meteorologisk Institutt met.no

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 Meteorologisk Institutt met.no

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 Meteorologisk Institutt met.no
