UAV, Vertical Profiling, Gas Sensing, AQ monitoringAbstract
Unmanned aerial vehicles (UAVs) have recently introduced simple methods for assessing and monitoring above-ground-level (AGL) air quality. This is possible due to their vertical accuracy and geo-special data collection capability. An extensive review of vertical profiling is necessary because various elements of the atmosphere, such as wind speed, Temperature, Rh(Relative Humidity), wind direction are crucial in controlling atmospheric processes. Many applications of drone-aided systems are upcoming to monitor the natural (i.e. forest, wildlife, wildfires, volcanic eruptions) and anthropogenic (i.e., urban life, industrial processes, mineral extraction, transport, and energy sector, waste management and wastewater treatment; agriculture) activities.
This paper deals with the significant literature on the drone economy, drone-aided AQ (Air Quality) monitoring and its applications for various AQ parameters. The review work focused on the type of UAVs used for the experiments, flight time and scope to improve battery life, available sensors, monitoring AGL height and application of ambient AQ monitoring. The scope for fusion with AI and the challenges of this technology are also discussed. Finally, the review identified the research gaps in drone-aided air quality monitoring and future research directions in air quality monitoring and sampling.
