| Description: |
Trends occurring at the extremes of Ozone distribution are often not reported even though these may be very different than the trend observed at the mean or median and they may be more relevant to health outcomes. Here researchers classify days of observation over a 16-year period into broad categories that capture salient daily local weather characteristics. They determine the rate of change in mean and median O3 concentrations within these different categories to assess how concentration trends are impacted by daily weather.
