Real time air quality data

Historic and live air quality data. NOx data are from chemiluminescent NOx analysers (API T200) operated by Bristol City Council since 2000. PM10 data are from a BAM 1020 instrument with an unheated head and are corrected to gravimetric. Hourly observations of oxides of nitrogen (NOx), nitric oxide (NO), nitrogen dioxide (NO2) and PM10 are shown. Data older than the current month have been ratified and corrected in accordance with UK air quality guidance LAQM TG.16.
