November 11, 2019 Marcel Workamp recently presented some of the experimental work under WP3 to a Dutch working group on quality of air measurements, called Platform Kwaliteit Luchtmetingen (PKL)in October 2019. PKL is hosted by the National Knowledge Center for Environmental Legislation (InfoMil). The presentation, Gevolgen van stromingsverstoringen op debietmeting in nauwe schoorstenen / Flow-Measurement Errors in Narrow Stacks (in Dutch) was also distributed to the Dutch standardization committee NC 390030 in November 2019. The Air Quality Measurement Platform (PKL) was established in 2004 to improve the quality of air measurements. The PKL identifies and identifies bottlenecks, initiates projects, encourages new developments and advises on monitoring. The presentation is available here, and also over on our Documents and publications page.
