      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 metrics 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.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 allow for new insights into the global
                      distribution, and seasonal and long-term changes of
                      tropospheric ozone. 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.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 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.},
