European exchange of air quality monitoring meta information in 2002

The results of the reporting cycle presented in this particular report  cover data for 2001. This report contains information delivered by EU Member States, and EFTA states, and Switzerland and Accession Countries, who have agreed to follow the data exchange procedures.

Nearly all the countries that have updated their meta information used the Air Quality Data Exchange Module (DEM), made available for this purpose by the European Topic Centre on Air and Climate Change (ETC/ACC). A total of 30 countries, including 14 EU Member States, provided air quality data for 2002. As in preceding years, a large number of time series were transmitted, covering, for example, sulphur dioxide (SO2), nitrogen dioxide (NO2), particulate matter (PM10), ozone (O3), carbon monoxide (CO) and benzene (C6H6).

Although most countries provided 2002 data only, several did provide data from previous years. These were loaded into AIRBASE as well. AIRBASE contents are overviewed elsewhere in this report to help other Member States to identify and fill historical data gaps, as requested in Article 5(4) of the European Council Decision on Exchange of Information.
