Open Access Theses & Dissertations
SARS-CoV-2, also known as COVID-19, was discovered in Wuhan, China in late 2019and spread rapidly worldwide in 2020. The COVID-19 pandemic and its quarantine periods influenced the number of people using their vehicles and the number of miles traveled, which correspondingly influenced the air quality of urban areas. The influence of the restrictions caused by the quarantine period on air quality differs from location to location. Previous research accounted for countries, but no research was done at the state level individually. This research attempts to evaluate the transportation-related air quality during the COVID-19 pandemic period using data from the Texas …

The emergence and rise in popularity of low-cost sensors for atmospheric observation aresetting a new precedent in identifying emission hotspots and providing high-resolution spatial and temporal data. Furthermore, low-cost sensors are becoming popular among institutions and the public, allowing community scientists to become more involved in air quality monitoring. However, concerns about the accuracy and precision of low-cost sensors have been questioned. Most recent research has focused on the utility of real-time monitoring and calibration requirements for these sensors. A low-cost monitoring project has deployed sensors in the El Paso del Norte region in low and high annual average daily …
