Source apportionment of pollution on Breathe London map
The Breathe London map now shows how different polluting activities contribute to the concentration of nitrogen oxides at Breathe London sensor locations across the city. Just search for or click on any sensor.
CERC modelled pollution sources across London for 2019 using our ADMS-Urban software to quantify the contributions from twenty source categories at different points. We integrated the modelling output onto the Breathe London map developed by CERC. This is the first time hyperlocal modelled source apportionment data has been displayed alongside current pollution measurements on an interactive public map. With a better understanding of which activities are causing pollution, leaders and communities can develop targeted solutions that clean the air and protect public health.
Starting today the Breathe London map also shows air quality alerts from CERC's airTEXT forecasting service for London and the South East.
Breathe London is a consortium led by the Environmental Defense Fund, including CERC, Air Monitors, University of Cambridge, National Physical Laboratory and Google Earth Outreach.
