Outline of Final Research Achievements

In this study, we tried to perform vertical flux measurements of atmospheric aerosols based a gradient method using two unmanned aerial vehicles (UAVs) measuring atmospheric aerosols and meteorological parameters (e.g., horizontal wind speed). We evaluated the methods to accurately observe aerosol concentrations and meteorological parameters on a drone, one of UAVs, and then, performed their airborne observations using two drones in Yokosuka city, which is located to an industrial area, Japan. Through the rigorous verification, we found that we successfully conducted the aerosol flux measurements in three cases in total. To the best of our knowledge, this is the first time to evaluate the aerosol flux using UAVs.

Academic Significance and Societal Importance of the Research Achievements

温室効果気体・大気エアロゾルといった大気組成成分について、濃度だけでなく、移動量(フラックス)の観測も数値モデルの検証・精緻化に強く求められてきたものの、これまで場所・設備の問題から観測は制限されてきた。本研究では、大気エアロゾルを対象として、沈着および放出を調べるための鉛直フラックス計測をドローンを用いて実現させることで、これまでの制限を超えるフラックス観測点の拡張を目指した。現時点では定量されたフラックス量に不確かさもあるが、ドローンを用いたフラックス観測の可能性を世界で初めて示すことに成功した。これまでに利用されてきたタワー・航空機観測と比べて圧倒的に低コストであり、この意義は大きい。
