Abstract:	美國國家學院(United States National Academies)於2018年發表關於地球觀測的十年戰略報告中提到，對行星邊界層(PBL)和低層對流層之掌握，具有科學的急迫性。本計畫提出以無人機系統(Unmanned Aerial System)作為低層大氣觀測的主要工具，參與7-SEAS國際觀測實驗，探討中南半島春季生質燃燒氣膠的垂直擴散、跨邊界層傳送及氣膠與雲交互作用等科學問題。本計畫將分析2019年泰國清邁無人機觀測資料，探討氣膠垂直分布與氣象因子之相關性，解釋氣膠在PBL熱動力機制的影響下之垂直擴散及演化行為，並嘗試定性或定量PBL污染物與自由大氣間空氣進行交換的過程。除此之外，本計劃將發展無人飛機具備解析自由大氣層對邊界層的逸入作用(entrainment)及氣膠與雲交互作用(aerosol-cloud interaction)之觀測技術，並具體應用於2020年越南安沛觀測實驗。最後，我們將整合無人機觀測觀測、地面遙測及衛星遙測，以觀測資料建立氣膠與雲交互作用的實證，輔助未來模式模擬的發展。 ;The United States National Academies published a ten-year strategic report on Earth observation in 2018 that mentions the scientific urgency of mastering the planetary boundary layer (PBL) and the lower troposphere. The project proposes the Unmanned Aerial System as the main tool for low-level atmospheric observations, participating in the 7-SEAS international observation experiment, and exploring the scientific topics of the vertical diffusion, trans-PBL transport and aerosol-cloud interaction of springtime Indochinese biomass-burning aerosols. We will analyze the data from 2019 Chiang Mai UAV experiment. From the data analysis, we will explore the correlation between the aerosol vertical distribution and meteorological factors, explain the vertical diffusion and evolution behavior of aerosol plume under the influence of PBL thermodynamic mechanism. We will also try to study the process of air exchanging between PBL and free atmospheric air either qualitatively or quantitatively. In addition, we will develop an unmanned aircraft with an observational capability to resolves the entrainment of the free atmosphere to the PBL and the aerosol-cloud interaction. The UAV implementation will be specifically applied to the 2020 7-SEAS field deployment in Yen Bai, Vietnam. Finally, we will integrate UAV, ground-based remote sensing and satellite observation to assess the research topic of aerosol-cloud interactions, and assist in the development of future model simulation.
