Glasgow University Indicators Paper Prepared by Anna Lisa Bondi, Duncan Lee and Marian Scott of the Department of Statistics. A review of the Scottish Trends analysis methodology and results. A draft paper based on hourly PM 10 downloaded from the website has been provided and concludes the following: Results are very similar to those produced by AEA (within 1  g/m 3 ) Small differences are probably due to rounding method and treatment of negative TEOM data. The indicator is robust (4  g/m 3 range) if 4 sites are used, and extremely robust (1.4  g/m 3 range) if seven sites are used.
