Uncrewed Aerial Vehicles (UAVs) equipped with handheld air quality monitors offer a novel approach to capturing vertical profiles of pollutants, bridging the gap between ground-level and satellite-based measurements. This thesis investigates the reliability of UAV-based observations for assessing air quality, addressing the potential impact of UAV movement and turbulence on sensor readings, the consistency of UAV-based measurements with ground-level measurements, and the influence of atmospheric dispersion on pollutant transport. Experimentation in Chapter 3 demonstrates that neither movement nor turbulence significantly affect the sensor's ability to capture reliable carbon dioxide (CO2) measurements, establishing a foundation for further exploration of UAV-based monitoring. Building on this foundation, Chapter 4 evaluates the reliability of UAV-based CO2 measurements at various altitudes compared to ground-level measurements. Findings indicate a high degree of agreement between UAV-based and ground-level measurements, supporting the use of UAVs for monitoring CO2 in the lower troposphere. This consistency across altitudes reinforces the validity of UAV-based measurements for capturing vertical profiles. Chapter 5 extends the investigation to nitrogen dioxide (NO2), a pollutant with more dynamic behaviour than CO2. By capturing vertical profiles of NO2 near a major highway under varying atmospheric dispersion conditions, this chapter reveals distinct vertical profiles under poor and good dispersion conditions. This highlights the influence of atmospheric stability on pollutant transport and demonstrates the ability of UAVs to capture these nuances. The findings of this thesis validate the use of UAVs equipped with handheld air quality monitors for capturing reliable vertical profiles of pollutants. The results of the experimentation conducted contribute to a better understanding of air quality dynamics in the lower troposphere and support the integration of UAV-based observations into air quality monitoring and exposure assessment studies. Future research should focus on expanding UAV-based monitoring to diverse environments and pollutants, refining measurement techniques, and integrating UAV data with other monitoring approaches to create comprehensive air quality models.
