Two Google Street View cars, equipped with reference-type air quality monitors, are measuring air pollution over approximately 600 eight-hour shifts between autumn 2018 and autumn 2019. The cars use fast-response, research-grade instruments to precisely measure pollution concentrations approximately every 1-10 seconds. Pollutants measured include black carbon (BC), CO₂, NO, NO₂, O3, PM2.5 (and other PM size ranges) on a variety of Londo...

The Breathe London stationary network is made up of 100 AQMesh pods, each containing a collection of small sensor-based air quality monitors that offer near real-time localised air quality information. They measure nitrogen dioxide (NO₂) and nitric oxide (NO) using electrochemical sensors; particulate matter (PM) in various size cuts (PM₂.₅ and PM10 are reported) using a light-scattering optical particle counter; and carbon dioxide (CO₂...

The data shows roadside and background average readings for Nitric Oxide, Nitrogen Dioxide, Oxides of Nitrogen, Ozone, Particulate Matter (PM10 and PM2.5), and Sulphur Dioxide. Measured in Micrograms per Cubic Meter of Air (ug/m3). The spreadsheet shows which Index level each reading falls in, and contains charts showing pollutant levels by time of day per month. Trend graphs of Nitrogen Dioxide and Particulate Matter PM2.5 are on th...

The LAEI 2010 has since been superseded. Click here for the full list of releases. There are 187 Air Quality Focus Areas in the Capital. These are locations that not only exceed the EU annual mean limit value for NO2 but are also locations with high human exposure. The Focus Areas were defined to address concerns raised by boroughs within the LAQM review process and forecasted air pollution trends. This is not an exhaustive list of Lon...

This is a dataset of air quality exposure data broken down by parliamentary constituency based on the current 2013 data from the London Atmospheric Emissions Inventory. The legal limit for NO2 is an average annual concentration of 40 ug/m3.

There are 187 Air Quality Focus Areas in London. These are locations that not only exceed the EU annual mean limit value for NO2 but are also locations with high human exposure. The Focus Areas were defined to address concerns raised by boroughs within the LAQM review process and forecasted air pollution trends. This is not an exhaustive list of London’s hotspot locations, but where the GLA believe the problem to be most acute.   1. ...

On his election in 2016, the Mayor committed to a large scale consultation on a range of actions to address poor air quality in London. Measures under consideration include implementing the Ultra Low Emission Zone (ULEZ) in 2019 rather than 2020, expanding the boundaries of the ULEZ, and introducing an Emissions Surcharge on the most polluting vehicles driving in central London from 2017. In addition the Mayor has committed to cleaning ...

Borough Tables from Understanding the Health Impacts of Air Pollution in London report. King’s College London, commissioned by the Greater London Authority and Transport for London, have calculated the health impacts associated with the air pollutant nitrogen dioxide (NO2) in London. This new study shows that in 2010 there was the equivalent of up to 5,900 deaths across London associated with NO2 long term exposure. (Please note: thes...

The LAEI 2006 has since been superseded. Click here for the full list of releases. Modelled NO2 annual mean concentrations in London for the year 2006. Calculations are based on the 2006 London Atmospheric Emissions Inventory (LAEI) and use three different meteorological scenarios (2003, 2004 and 2006). This dataset can be mapped in a Geographic Information System (GIS) using the corresponding 20m grid or point datasets also available ...

The LAEI 2006 has since been superseded. Click here for the full list of releases. Modelled PM10 exceedance days in London for the year 2010. Calculations are based on the 2006 London Atmospheric Emissions Inventory (LAEI) and use three different meteorological scenarios (2003, 2004 and 2006). This dataset can be mapped in a Geographic Information System (GIS) using the corresponding 20m grid or point datasets also available on the Da...
