Summary

Description

Concentration Modelling has been produced by the Environmental Research Group, Kings College London, using the LAEI 2008. Pollutant maps for the Greater London area have been produced for the years 2008, 2011 and 2015. Emissions data contained within the [LAEI 2008](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/laei-2008) can also be downloaded from the Datastore _Technical Information_ 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. Data will be made available in other formats and structures (such as generalised contours which are faster to draw) in due course. **Pollutant** **Illustrative Map (jpg)** **20m grid (shapefile)** **20m grid (tab file)** NO2 Annual Mean [2008](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-no2am-2008.jpg) [2011](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-no2am-2011.jpg) [2015](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-no2am-2015.jpg) [Download file ](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/datafiles/environment/laei-2008-no2a-20mgrid-shp.zip)(147mb zipped) n/a NOx Annual Mean [2008](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-noxam-2008.jpg) [2011](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-noxam-2011.jpg) [2015](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-noxam-2015.jpg) [Download file ](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/datafiles/environment/laei-2008-noxa-20mgrid-shp.zip)(150mb zipped) n/a PM10 Annual Mean [2008](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-pm10am-2008.jpg) [2011](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-pm10am-2011.jpg) [2015](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-pm10am-2015.jpg) [Download file ](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/datafiles/environment/laei-2008-pm10a-20mgrid-shp.zip)(142mb zipped) n/a PM10 Exceedence [2008](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-pm10e-2008.jpg) [2011](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-pm10e-2011.jpg) [2015](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-pm10e-2015.jpg) [Download file](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/datafiles/environment/laei-2008-pm10e-20mgrid-shp.zip) (148mb zipped) n/a PM25 Exceedence [2008](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-pm25e-2008.jpg) [2011](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-pm25e-2011.jpg) [2015](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/images/laei-2008-pm25e-2015.jpg) [Download file ](https://s3-eu-west-1.amazonaws.com/londondatastore-upload/datafiles/environment/laei-2008-pm25e-20mgrid-shp.zip)(140mb zipped) n/a
