Estimation of trends in high urban ozone levels using the quantiles of (GEV)
AbstractIn this paper we propose a statistical methodology to analyze the trends of very high values of tropospheric ozone. The methodology is based on the estimation of percentiles of the distribution of extreme values. The asymptotic distribution of the estimated percentiles is obtained with a normal result. This allows us to use a linear regression to investigate linear and non‐linear trends. To illustrate the proposed methodology we use the information on ozone levels from some monitoring stations in Mexico City during the period from 1986 to 2005. The analysis of the information indicates a decrease in the very high ozone levels in the later years. Copyright © 2009 John Wiley & Sons, Ltd.
