Text description of figure
Figure 13.5 shows a comparison between PM10 concentrations measured using a BAM and a TEOM with a 30°C sample temperature at St Alban's Christchurch.
The first chart shows data from October to March 1998 (summer). There is no discernible pattern. The second chart shows data from April to September 1998 (winter). The TEOM readings are lower than the BAM readings with a very good correlation (R2=0.96) between the two methods.
