Air Quality Monitoring - NO2 Diffusion Tube Data 2019
Monthly and annual averages for the calendar year 2019 of NO2 mean concentrations (µg/m3) from diffusion tubes across Cheshire East. NOTE - a figure of zero (0) indicates that there is no data for that month. All raw data is subject to Defra approved bias corrections and distance corrections where applicable. These two corrections are applied to the end of year annual average not the monthly data. As such the annual average will be different from the running average displayed here.
