This paper compares PM 10 mass concentrations data generated by three co-located particulate monitors, the tapered element oscillating microbalance (TEOM 40) (operating at 40 °C), MiniVol and DustTrak, operating outdoors during winter woodsmoke air pollution (Christchurch, New Zealand). TEOM 40 data were adjusted to adjTEOM 40 with an algorithm derived from a co-located TEOM 40 and HiVol at a second field site. Corrected and corrected-log e-transformed data were analyzed with reduced major axis regression. Logged adjTEOM 40 and DustTrak data correlated best ( r 2 = 0.8 1 ) but the DustTrak required a substantial correction factor to make data comparable in real terms. Consistent over-recording by the DustTrak and under-recording by the TEOM 40 were consistent with previously published work. The MiniVol did not correlate well with other instruments ( r 2 = 0.6 2 and 0.53 against the adjTEOM 40 and DustTrak, respectively) but reasons for this cannot be ascertained.
