Air Quality in Bristol | NO² Map | NO² Table | Continuous Monitoring

This site aims to gather and visualise data on Air Quality in Bristol. Currently it provides :

A Map showing NO² Annual average readings from diffusion tubes for the years 2013 to 2016. The acceptable limit for this pollutant according to the European Standard is 40 µg/m3.
The same data in Table form
A page for each site eg Bishop Road
A list of the current continuous monitoring stations

Colour Coding

The colour coding uses a gradient rather the simple 3 colour banding used in the ClairCity maps.

These are sample points in that gradient:
NO² Annual measurements in µg/m3 0 10 20 30 40 50 60 70 80 90
