On Friday 20th June, the Air Quality in Scotland website was updated to include new versions of several LAQM tools. These include:
- A new Emission Factor Toolkit (EFT v6.0). The EFT allows users to calculate road vehicle pollutant emission rates for NOx, PM10, PM2.5 and hydrocarbons for a specified year, road type, vehicle speed and vehicle fleet composition. CO2 emission rates can also be calculated for petrol and diesel fuelled vehicles. The latest version uses updated NOx and PM vehicle emission factor – speed equations (COPERT 4v10) and fleet composition data.
- New background maps based on 2011 with projections from 2011 to 2030.
- An updated version of the NOx-NO2 Calculator (v4.1).
These latest LAQM tools can be found at http://www.scottishairquality.co.uk/laqm/tools with the new background maps available at http://www.scottishairquality.co.uk/data/mapping?view=data.
