Non-automatic Monitoring Data • Still awaiting site co-ordinates from some local authorities. • Example of display of diffusion tube site locations and graphing currently under development

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.
