Frenchay NOx
When fossil fuels like oil, coal and natural gas are burned a mixture of oxides of nitrogen, primarily nitric oxide (NO) and nitrogen dioxide (NO2), collectively termed NOx are released into the atmosphere. Nitrogen oxides like nitric oxide (NO) and nitrogen dioxide (NO2) can react in the air to produce ozone and other harmful pollutants that lead to smog. Nitrogen dioxide emissions can also be further oxidised in air to acid gases, which contribute to the production of acid rain
Displayed below are NOx 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
