A Lufft WS500 weather station is incorporated into the instrument to provide co-located meteorological measurements. Alternatively, particle mass concentrations can be produced as PM1, PM2.5 and PM10 measurements. The instrument measures the size and number density of aerosol molecules by using a 0.5m vertical inlet to suck ambient air into a measurement chamber. The scattering of a laser beam transmitted through the chamber is used to deduce size and concentration information. It is operated continuously on the roof of a cabin at a height of 8m above ground at the Chilbolton Observatory site. Measurements are taken every 60s, providinga erosol particle concentration (counts/m3) in 31 size bins in the range 0.265-34.0 um, air temperature, relative humidity, air pressure, wind speed and wind direction. The instrument is calibrated every 18 months by the manufacturer Agnew, Judith Unavailable author Unavailable author NCAS British Atmospheric Data Centre (NCAS BADC) custodian +44(0)1235 446432 British Atmospheric Data Centre STFC Rutherford Appleton Laboratory Harwell Oxford OX11 0QX UK badc@rl.ac.uk custodian NCAS British Atmospheric Data Centre (NCAS BADC) distributor +44(0)1235 446432 British Atmospheric Data Centre STFC Rutherford Appleton Laboratory Harwell Oxford OX11 0QX UK badc@rl.ac.uk distributor Walden, Chris J.
