Graphics of annual values NABEL
The National Air Pollution Monitoring Network (NABEL) measures air pollution levels at
16 locations in Switzerland and monitors the development over the past few decades. The
stations are distributed throughout the country and monitor pollution at typical locations
(e.g. city-centre streets, residential areas, rural stations).
Time series data older than 1990 often exhibit gaps of a certain length. As pollutant concentra-
tions vary considerably throughout the year, theses gaps cannot be simply ignored. The data
series were therefore completed as follows: the monthly averages were calculated, then the
missing monthly averages were obtained by linear regression of data series from another meas-
uring station exhibiting similar variation over time, and finally, providing there were at least at
least four valid monthly averages available for the station, the yearly average was then calculat-
ed from these values. Isolated gaps in the data series of the stations of Basel-Binningen (NO2)
and Dübendorf (SO2) were interpolated directly by linear regression of the yearly averages.The
Bern measuring station had to be moved in 1997, though it remained along the same thorough-
fare hemmed in by tall buildings. The resulting inconsistencies in the time series were corrected.
