During the period 28 Feb – 4 March 2010, thirteen air quality monitoring stations in Scotland recorded moderate or higher concentrations of PM10. However, only one of these stations was part of the UK national network (the Automatic Urban and Rural Network, AURN) and all others were local authority monitoring stations within the Scottish Air Quality Database (SAQD).

This short report investigates the nature of this pollution event and why it was seen so widely across the Scottish Database stations but not so at the AURN stations.
