Air Monitoring System
Frenchay NO
Is the most common form of nitrogen directly emitted into the atmosphere. In ambient outdoor air, nitric oxide (NO), which is emitted by motor vehicles, combines with oxygen in the atmosphere under the action of sunlight, producing nitrogen dioxide (NO2) -a major air pollutant- and other NOx.
Displayed below are NO Graphs (Current, Yesterday, Last week and Last Month) with links to the raw data by clicking on the graph. Should any Academic or Group require more specific or a wider range of data please contact estates
Info: Conversion rates from ppb to µg/m3 are from the latest Local Air Quality Management Technical Guidance LAQMTG(09). They are:
NO 1 ppb = 1.25 µg/m3
NO2 1 ppb = 1.91 µg/m3
NOx are expressed as NO ppb + NO2 ppb x 1.91
O3 1 ppb = 2.00 µg/m3
