Objective To create a complete 3-D hourly ozone data set covering the whole troposphere over Europe for a summer period of 6 months and to analyze this ozone data set to investigate the different ozone patterns and its controlling phenomena in the different areas in The ozone data set will be made using available experimental data (ground level and vertical soundings), by performing dedicated vertical soundings and by using available ozone data from satellites (GOME-instrument). A data-assimilation technique will be developed which, using available 3-D tropospheric Eulerian grid photo-oxidant models, and the experimental data set, will lead to a complete coherent and consistent 3-D hourly ozone data set over Europe. The data set will be created for the months of April until September (6 months) of the year 1997. With this data set, ozone budget studies to reveal differences between the North Sea/Atlantic and the Mediterranean Sea (local production versus long range transport, and the influence on the coastal areas) will be performed. Also vertical fluxes between the planetary boundary layer and the free troposphere, and the troposphere and the stratosphere will be analyzed; also the representativeness of the vertical soundings performed will be investigated.
