AirBase is the public air quality database 
                          system of the EEA. It contains a information submitted 
                          by the participating countries throughout Europe.
                        The air quality database consists, 
                          next to multi-annual time series of air quality measurement 
                          data and their statistics for a representative selection 
                          of stations and for a number of pollutants, also meta-information 
                          on the involved monitoring networks, their stations, 
                          and measurments. 
                        The database covers geographically 
                          all countries from the European Union, the EEA member 
                          countries and some EEA candidate countries. The EU countries 
                          are bound to report under the Council Decision 97/101/EC, 
                          a reciprocal Exchange of Information (EoI) on ambient 
                          air quality. Whereas, the EEA member countries committed 
                          themselves to report to the EEA following this EU-legislation 
                          or develope the appropriate measuring and reporting 
                          infrastructure following EEA's EuroAirnet programme 
                          critiria. All data reported within EuroAirnet context 
                          are included in the database. 
                        AirBase replaced and continued on the 
                          fundaments of two preceding EU databases: 
                          APIS (Air Pollution Information System; air quality 
                          data) 
                          GIRAFE (meta information on air quality networks and 
                          stations)
