| Abstract: |
| Objective To design an atmospheric pollution observation platform that can be used around the atmospheric boundary layer. Methods A multi-rotor UAV was used as a carrier to integrate a variety of portable devices for measuring at-mospheric pollutants and meteorological parameters to build a UAV observation platform. Through ground comparison experiment, the data measured by the portable devices were considered as reliable. The data reliability of the integrated platform was verified by a vertical comparison experiment with the large-loaded tethered balloon platform. Results For the main observation indicator PM2.5, the vertical profiles obtained by the UAV and the tethered balloon showed good consistency. Even the lowest R-square value of each flight reached 0.761, and the intraclass correlation coefficient (ICC) of most flights reached more than 0.94. In the case of December 18, 2017, the observation data showed that there was a significant stratification of the atmospheric vertical structure in the morning, and the relatively stable atmospheric layer at 0-200 m hindered the upward dispersion of air pollutants, resulting in a concentration of PM2.5 at 80 μg/m3 near ground. The observations in the afternoon also helped explain the dissipation process of air pollution. Conclusion The multi-rotor UAV platform built in this paper can be used for boundary layer observations in the range of 0-1000 meters. Although there is still some differences between the data measured by UAV and tethered balloon in some cases, the existing observation results show that the platform is helpful for understanding the occurrence and dissipation of air pollution. This platform can be further promoted and applied in other places. |
