This file includes all DEFRA automatic urban and rural network PM2.5 monitoring sites by name, code, lat, lng, site_type (urban, rural etc), and postcode. They are correct as of 21 December 2020.
Sites were downloaded through the OpenAir R package (with thanks to David Carslaw). Postcodes were assigned using the LocationIQ reverse geocoding API. Where postcodes were not correctly assigned (as in 24 cases) the latitudes and longitudes were assessed manually using Google Maps.
Note that these are only sites monitoring PM2.5, not necessarily other pollutants.
