Sydney Particle Study 2 - Aerosol and gas data collection
The observations of the Sydney Particle Study (SPS) were carried out in two stages at the Westmead Air Quality Station by teams of scientists from CSIRO, OEH, and ANSTO. Stage 2 (SPS2) was in autumn 2012 (from 16 April to 14 May 2012). SPS2 involved a comprehensive suite of measurements of atmospheric gases and aerosols in order to better understa... morend the source, the chemical composition and the size distribution of the aerosol and gas-phase secondary aerosol precursors in Sydney.

The sampling program included the measurement of particles, criteria and acid/alkaline gases, speciated VOCs, radon and meteorological parameters. Measurement of particles involved continuous or semi-continuous measurements of aerosol number size distributions, aerosol mass, aerosol light scattering and aerosol composition. Gas-phase secondary aerosol precursors were measured by integrated or continuous measurements of criteria gases (NOx, CO, SO2 and ozone), acid/alkaline gases (NH3, SO2, HCl and HNO3) and speciated VOCs (including carbonyls). Continuous measurements of meteorological parameters temperature, relative humidity (RH) and wind speed/direction were made during the measurement campaigns.
The integrated samples of particles, VOCs and acid/alkaline gas were collected during two periods of each day for most of the measurements; a morning sample was collected between 05:00 and 10:00 and an afternoon sample was collected between 11:00 and 19:00 each day. A third VOCs (adsorbent tube/DNPH sampling) sample was collected overnight between 19:00 and 05:00.
