Ranked measured concentration
Fig. 3. St Albans measured daily PM 10 (μg/m 3 ) in rank order (line) and the corresponding
modeled concentrations (points). Spearman rank correlation coefficient 0.80. May-August 2005
and 2006, days 8°C or lower
CALMET has been shown to effectively develop the terrain induced surface
flows that affect Christchurch on light-wind evenings. The CALPUFF modeling
of wintertime PM 10 in the city has been verified against measured data at two sites
and whilst daily values are generally too high, the model captures diurnal variability
