Disclaimer: Please note, the data for 2022 on following links provide RAW, direct from the monitors. It has not been corrected to account for monitor drift or equipment failures, some data may therefore show non-representative values. The data is for information only. Levels exceeding the long term annual average objective (40 micrograms per cubic metre for NO2) may be classed as 'low' based on the national short term objectives (Daily Air Quality Index).
Recent data from the live monitoring sites can be downloaded from UK Air Quality website.

Bath and North East Somerset Council also have a network of over 160 diffusion tubes locations across the area, these measure monthly nitrogen dioxide concentrations. These are collected once a month and taken to a laboratory. The data for these diffusion tubes is contained in the Annual Status Report and mapped on our 'Air Quality Data - Long-Term' page.
