English Abstract From August 1992 until july 1993, ozone quality control
measurements were carried out in the Dutch National Air Quality Monitoring
Network (LML). Measurement results from 17 LML measurement locations were
compared with those from a reference monitor. It can be concluded that on
average ozone levels from the LML give an underestimation of 4,9%, which is
independent of the absolute measured levels. In some cases, deviations up
to 20% are found suggesting the need for further
investigation.
