GIS major Noah Holderbaum presented his Provost's summer URECA fellowship project on October 2. His project looked at the connections between urbanization, air pollution, and demographics in Houston and Phoenix.
Noah’s official description of the project:
This research examines the relationship between changes in air pollution, demographics, and urbanization in the cities of Phoenix, Arizona and Houston, Texas between 2000 and 2022. Air pollution data from the Washington University’s Atmospheric Composition Analysis Group’s SATPM2.5 V5.NA.05 model was used, while demographic data was obtained from the 2000, 2010, and 2020 decennial censuses through IPUMS NHGIS. Urbanization data was received from the National Land Cover Database’s Land Cover and Percent Impervious Surface products. Using these sources, this study aims to determine spatiotemporal trends in air pollution as well as explore connections between air pollution, demographics, and urbanization. This research also looks at variations between these relationships between different time periods and neighborhoods within the two study areas.
We are very proud of Noah’s accomplishment and grateful to have him as member of the DGES community.
