LLAQM bespoke borough by borough 2013 air quality modelling and data

The new bespoke borough packages provide a set of maps, data and graphs in order to facilitate the usability of LAEI 2013 data.

Modelling and emission data from the LAEI 2013 has been used for NO_x, NO₂, PM₁₀ and PM_2.5.

All boroughs can download the following files:

• Excel Tools
  • LLAQM Source Apportionment, providing emissions split by source at a chosen location (1km² resolution) - 14/04/16 Update: Please note that the Source Apportionment tool has been updated (v1.1 - providing a breakdown of emissions at Borough level as well).
  • Borough table showing population and percentage of population within areas where NO₂ concentrations are greater than 40µg/m³
• Greater London Concentration Maps (PDF and JPEG) - Greater London maps showing NO₂, NO_x, and PMs concentrations for 2013, 2020, 2025 and 2030 - 11/07/16 Update: Please note that maps for future years have now been uploaded.

 Separately, each borough package includes the following for 2013 and 2020 (PDF and JPEG):

• NO2_AnnualMean_Conc1 - Borough maps showing NO₂ concentrations
• NO2_AnnualMean_Conc2 - Borough maps showing NO₂ concentrations with a basemap
• NO2_AnnualMean_exc - Borough map showing areas where NO₂ concentrations are greater than 40µg/m³ and 60µg/m³
• NOx_AnnualMean_Conc1 - Borough maps showing NO_x concentrations
• NOx_AnnualMean_Conc2 - Borough maps showing NO_x concentrations with a basemap
• PM10_AnnualMean_Conc1 - Borough maps showing PM₁₀ concentrations
• PM10_AnnualMean_Conc2 - Borough maps showing PM₁₀ concentrations with a basemap
• PM10d_NoDOver50_Conc1 - Borough maps showing PM₁₀ daily mean concentrations over 50µg/m³
• PM10d_NoDOver50_Conc2 - Borough maps showing PM₁₀ daily mean concentrations over 50µg/m³
• PM2.5_AnnualMean_Conc1 - Borough maps showing PM_2.5 concentrations
• PM2.5_AnnualMean_Conc2 - Borough maps showing PM_2.5 concentrations with a basemap
• Borough dashboard emission summary (table and graph) by source type for all years, for NO_x, PM and CO₂  - 22/03/16 Update: Please note that the dashboards have been updated to correct an error in PM₁₀ 2030 totals for the "Other" emissions category.

11/07/16 Update: Please note that maps for 2020 have now been included in the borough packages.
