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...

These ward level well being scores present a combined measure of well-being indicators of the resident population based on 12 different indicators. Where possible each indicator score is compared with the England and Wales average, which is zero. Scores over 0 indicate a higher probability that the population on average will experience better well-being according to these measures. Users can adjust...
