Abstract

This report presents the results of measuring ground-level ozone (03), suphur dioxide (SO2), nitrogen monoxide (NO), nitrogen dioxide (NO2) and carbon monoxide (CO) in the Trolix '91 campaign, 10-28 june 1991, at the Dutch National Institute of Public Health and Environmental Protection (RIVM), Bilthoven, the Netherlands. The instruments used for measuring the aboven-mentioned compounds are respectively: an UV photometric 03-analyzer and a gas-phase fluorescence SO2 analyzer, a chemiluminescence NOx analyzer and a gas-filter correlation spectrometry CO analyzer. All compounds have been measured using a 1-min time resolution. Except for 03 all compounds concentration values are available from the RIVM National Air Quality Monitoring Network (LML). One of the LML stations is situated in Bilthoven. Unfortunately, due to a technical failure, between 10 and 19 june only hourly averages are available.
