Emissions in Ealing
London has one of the most comprehensive air quality monitoring networks of any global city and air quality is constantly monitored at over 150 locations.
These sites are operated and funded by the London boroughs, Transport for London (TfL) and Heathrow Airport.
All data from the reference air quality monitors in London are publicly available on either the London Air or Air Quality England websites, depending on which data manager the
borough subscribes to.
These websites include the monitor locations and dates they have been running, as well as all the pollution concentration data, which can be freely downloaded.
The London Borough of Ealing regularly reports on air quality monitoring in the borough, as per the requirements of the statutory London Local Air Quality Management process.
The GLA regularly reports on air quality trends in London. This reporting uses data from the city’s air quality monitoring network to analyse the long term trends in pollution concentrations (the levels of pollution in the air).
The most recent modelling is the London Atmospheric Emissions Inventory (LAEI) 2019.
This is a public dataset and includes modelled ground level concentrations of annual mean NOx, NO2, PM10 and PM2.5 in µg/m3 (microgramme per cubic metre) at 20m grid resolution.
