We have had the pleasure to be visited by KNMI (Royal Netherlands Meteorological Institute) representatives this week for a workshop on developing their novel NO2 sensor. We had a very productive workshop on practical design, measurement principles, project planning and also touching on eventual business ventures.
NO2 (Nitrogen dioxide) has a strong negative health effect. Due to a degradation time measured in minutes or hours and the low background levels, NO2 is a clear indicator of nearby pollution. The gas is almost exclusively produced from combustion, making the sources easy to pinpoint. This makes sampling NO2 suitable to make detailed maps of urban pollution.
