Cox, L. H., M. L. Thompson, J. Reynolds, P. Guttorp, AND P. Sampson. A Review of Statistical Methods for the Meteorological Adjustment of Tropospheric Ozone. ATMOSPHERIC ENVIRONMENT 35(3):617-630, (2001).

| Abstract:
|
A variety of statistical methods for meteorological adjustment of ozone have been proposed in the literature over the last decade for purposes of forecasting, estimating ozone time trends, or investigating underlying mechanisms from an empirical perspective. The methods can be broadly classified into regression, extreme value, and space-time methods. We present a critical review of these methods, beginning with a summary of what meteorological and ozone monitoring data have been considered and how they have been used for statistical analysis. We give particular attention to the question of trend estimation, and compare selected methods in an application to ozone time series from the Chicago area. We conclude that a number of approaches make useful contributions to the field, but that no one method is most appropriate for all purposes and all meteorological scenarios. Methodological issues such as the need for regional-scale analysis, the nonlinear dependence of ozone on meteorology, and extreme value analysis for trends are addressed. A comprehensive and reliable methodology for space-time extreme value analysis is attractive but lacking.
