<p></p> <blockquote><a href="/air-quality/">The LAEI 2008 has since been superseded. Click here for the full list of releases.</a></blockquote> <p>Concentration Modelling has been produced by the Environmental Research Group, Kings College London, using the <a href="/dataset/laei-2008">LAEI 2008</a>. Pollutant maps for the Greater London area have been produced for the years 2008, 2011 and 2015.</p> <p>Emissions data contained within the <a href="https://s3-eu-west-1.amazonaws.com/londondatastore-upload/laei-2008">LAEI 2008</a> can also be downloaded from the Datastore</p> <p><em>Technical Information</em></p> <p>This dataset consists of a series of very detailed GIS layers showing modelled concentration values for five different pollutants. Each zip file contains a 20 metre grid shapefile, mxd and layer files for use in ESRI ArcGIS software.</p> <p>Data will be made available in other formats and structures (such as generalised contours which are faster to draw) in due course.</p> <p><strong>Pollutant</strong> <strong>Illustrative Map (jpg)</strong> <strong>20m grid (shapefile)</strong> <strong>20m grid (tab file)</strong></p> <p>NO2 Annual Mean</p> <p>2008, 2011, 2015 and Download file (147mb zipped)</p> <p>NOx Annual Mean</p> <p>2008,&nbsp;2011, 2015, and Download file (150mb zipped)</p> <p>PM10 Annual Mean</p> <p>2008, 2011, 2015, and Download file (142mb zipped)</p> <p>PM10 Exceedence</p> <p>2008, 2011, 2015, and Download file (148mb zipped)</p> <p>PM25 Exceedence</p> <p>2008, 2011, 2015, and Download file (140mb zipped)</p>
