English Abstract In this report the results of an evaluation of the
technical performance of the Dutch National Air Quality Monitoring Network
in 1991 are presented. The average brute component efficiences, i.e. a
measure for the availability of measuring data, are: - for the automatically
measured components [CO, NOx, O3 SO2] 98%; - for the meteorological
parameters [global radiation, temperature, wind direction, wind speed]97%;
- for aerosols etc. [black smoke, acidifying compounds, metals, tsp.] 97%.
- for the chemical composition of precipitation [i.a. acidifying compounds
heavy metals] 97%. Current Dutch legislation requires the measurement of a
number of components in such way that only a minimal loss of data is
tolerated. The number of stations wich did not meet the legal requirements
in 1991 are: 3 for CO [12% of the total number of stations], 7 for NO2
[17%], 7 for SO2 [18%], 0 for lead aerosol and 9 for black smoke
[45%].
