Airbase European Air Quality Database Version 5, 2011

AirBase is the European air quality database maintained by the European Environment Agency (EEA). It covers all EU Member States (which are bound under Decision 97/101/EC to engange in a "reciprocal exchange of information (EoI)" on ambient air quality), the EEA member countries and some EEA collaborating countries. The database consists of a multi-annual time series of air quality measurement data and statistics for a number of air pollutants. It also contains meta-information on those monitoring networks involved, their stations and their measurements.
