Extreme value theory; Air -- Pollution; Particulate Matter; Ozone


In the last few decades, concerns regarding air pollution have led to many new laws and regulations being put into place to mitigate the e↵ects of pollution on the environment and humanity as a whole. This paper analyzes several decades’ worth of ground-level ozone readings in six of the largest metropolitan areas in Texas, using data from the United States Environmental Protection Agency (EPA). These regions include the Austin-Round Rock area, Corpus Christi, the Dallas-Fort Worth-Arlington area, El Paso, the Houston-The Woodlands-Sugar Land area, and the San Antonio-New Braunfels area. We identify trends in these readings using the Jonckheere-Terpstra test.
