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%].
