What is airTEXT?

airTEXT is a free service for the public providing air quality alerts by SMS text message, email and voicemail and 3-day forecasts of air quality, pollen, UV and temperature across Greater London. airTEXT is an independent service, operated by Cambridge Environmental Research Consultants (CERC) Ltd in partnership with a Consortium made up of representatives from all the member local authorities, the GLA, Public Health England and the Environment Agency. The airTEXT Consortium is chaired by Paul Clift, Environmental Health Manager at Islington Borough Council.

airTEXT air quality maps at 7m resolution are created using CERC's world-leading urban air quality dispersion modelling system ADMS-Urban.

Member local authorities pay a small annual subscription to be part of the service. The maintenance and development of the core airTEXT service is funded jointly by CERC and research projects in which CERC is involved. Grants from national and local government have contributed to airTEXT service developments in the past. airTEXT works in partnership with the GLA from time to time, for example on the Mayor's Breathe Better Together campaign.

How are the forecasts made?

The air quality forecasts are produced using CERC's air pollution forecasting system. Information from weather forecasts, forecasts of pollution across Europe and very detailed data on about 30,000 pollution sources across London are fed into the world-leading ADMS-Urban air quality model to produce forecasts of air quality at a high degree of spatial resolution (7m). The forecasts are updated twice a day at about 7am and 7pm. We compare the forecasts with observed pollution levels to assess the accuracy of the forecasts. These performance statistics are available here.

The hourly concentrations of four pollutants are calculated: nitrogen dioxide (NO2), particulates (PM10 and PM2.5) and ozone (O3). From the hourly concentrations the daily air quality index (DAQI) of each pollutant is derived. The overall air quality index is determined by the highest index for any of these pollutants.

airTEXT issues an alert for a local authority or region if at least 10% of the geographical area is predicted to reach MODERATE or above.

Forecast values of UV, grass pollen and temperature are supplied by MeteoGroup.
