Unmanned Aerial Vehicle Applications in Atmospheric Monitoring

Unmanned aerial vehicles (UAVs) have emerged as versatile platforms for in situ characterisation of atmospheric composition, bridging the gap between surface stations, manned aircraft and satellite observations. Equipped with miniaturised sensors, these systems can profile trace gases, particulate matter and meteorological parameters across the atmospheric boundary layer with high spatial and temporal resolution. Applications range from quantifying urban pollution plumes and industrial emissions to capturing vertical distributions of aerosols over remote regions and monitoring greenhouse‐gas fluxes in fragile ecosystems. Recent advances in sensor design, data‐fusion protocols and flight control software have extended flight endurance, improved payload stability and enabled autonomous missions in complex terrain. The ability to deploy rapidly at low altitude allows researchers to investigate emission hotspots, stratified layers and evolving haze episodes that would otherwise remain undersampled. Despite these gains, challenges persist in optimising sensor placement to mitigate rotor‐induced flow disturbances, ensuring calibration stability under varying temperature and pressure, and navigating evolving airspace regulations. As policies adapt and technology matures, UAVs are poised to become integral to operational air‐quality networks and climate research campaigns worldwide.
