摘要
Ozone and other air quality data from five rural sites in the industrialized Latrobe Valley, Victoria, have been subject to statistical analyses including linear regression modeling. The behavior of O//3 in the Latrobe Valley is explained largely in terms of natural background atmospheric processes as observed at Cape Grim, Tasmania. A comparison of observations from an elevated station (750 m) with those from the valley floor shows systematic differences in seasonal and diurnal O//3 variations and the time of day of occurrence of elevated O//3 concentrations which can be explained in terms of the diurnal cycle of convective mixing and mountain/valley winds. A linear regression model incorporating this understanding has accounted for between 43% and 64% of the variance of O//3 concentration at the elevated and rural stations. The standard deviation of the residual O//3 values (observed minus fitted) is around 5 ppb. Auto and cross correlations are used to show that perhaps half of the unexplained variance is coherent from site to site and hence potentially could be modeled.
