Mill Road Air Quality NO2

Pollutent Description

Combustion processes emit a mixture of nitrogen oxides (NOX), primarily nitric oxide (NO) which is quickly oxidised in the atmosphere to nitrogen dioxide (NO2). Nitrogen dioxide has a variety of environmental and health impacts. It is a respiratory irritant which may exacerbate asthma and possibly increase susceptibility to infections. In the presence of sunlight, it reacts with hydrocarbons to produce photochemical pollutants such as ozone. NO2 can be further oxidised in air to acidic gases, which contribute towards the generation of acid rain.

The data is available from 08/07/19 to 28/10/19.

The data in this release file is broken down by hourly increments.

The fields within the dataset are based around the individual serial numbers of the sensors. The location of the sensors, including the individual serial numbers, can be accessed here:
