      abstract     = {In support of the first Tropospheric Ozone Assessment
                      Report (TOAR) a relational database of global surface ozone
                      observations has been developed and populated with hourly
                      measurement data and enhanced metadata. A comprehensive
                      suite of ozone data products including standard statistics,
                      health and vegetation impact metrics, and trend information,
                      are made available through a common data portal and a web
                      interface. These data form the basis of the TOAR analyses
                      focusing on human health, vegetation, and climate relevant
                      ozone issues, which are part of this special
                      feature.Cooperation among many data centers and individual
                      researchers worldwide made it possible to build the world's
                      largest collection of in-situ hourly surface ozone data
                      covering the period from 1970 to 2015. By combining the data
                      from almost 10,000 measurement sites around the world with
                      global metadata information, new analyses of surface ozone
                      have become possible, such as the first globally consistent
                      characterisations of measurement sites as either urban or
                      rural/remote. Exploitation of these global metadata allows
                      for new insights into the global distribution, and seasonal
                      and long-term changes of tropospheric ozone and they enable
                      TOAR to perform the first, globally consistent analysis of
                      present-day ozone concentrations and recent ozone changes
                      with relevance to health, agriculture, and
                      climate.Considerable effort was made to harmonize and
                      synthesize data formats and metadata information from
                      various networks and individual data submissions. Extensive
                      quality control was applied to identify questionable and
                      erroneous data, including changes in apparent instrument
                      offsets or calibrations. Such data were excluded from TOAR
                      data products. Limitations of a posteriori data quality
                      assurance are discussed. As a result of the work presented
                      here, global coverage of surface ozone data for scientific
                      analysis has been significantly extended. Yet, large gaps
                      remain in the surface observation network both in terms of
                      regions without monitoring, and in terms of regions that
                      have monitoring programs but no public access to the data
                      archive. Therefore future improvements to the database will
                      require not only improved data harmonization, but also
                      expanded data sharing and increased monitoring in
                      data-sparse regions.},
