Summary

Modelled concentrations of annual average nitrogen dioxide (NO2) and particulate matter with diameter <2.5µm (PM2.5) were linked to postcode centroids in Greater London. The pollution values are joined to NWL Registered population using current postcode.

Documentation

Modelled concentrations (µg/m3) of annual average nitrogen dioxide (NO2) and particulate matter with diameter <2.5µm (PM2.5) were linked to postcode centroids in Greater London. Air pollution exposure estimates (i.e. concentrations) were derived using models developed for the year 2015 by overlaying the x,y location of postcode centroids with NO2 and PM2.5 maps (25m x 25m resolution) within a geographic information system (GIS). Following analysis of changes in air pollution measurements over time, using routine monitoring data from the DEFRA-run Automatic Urban and Rural Network (AURN), we made adjustments to the 2015 modelled concentrations to estimate 2010 to 2019 exposures using a method know as ‘differencing’ (Gulliver et al. 2013).

Access service description

Researchers will have access to a VDI environment with a specific username and password. The researchers will get access to the datasets that is present in the hub's catalogue and would be able to carry out their research within the safe haven. There are restrictions applied which prevents the researchers from taking data out of the safe haven, once the research/analysis is completed the admin team will need to be contacted for taking the analysis off the safe haven.
