| Abstract: | 過去六年(2012-2017)本計劃在科技部的補助下，完成許多具體的成果，針對東南亞生質燃燒與中國霾害等問題進行一系列的研究，共發表了38篇SCI論文著作，建構一套氣膠光學遙測技術及氣膠輻射效應估算方法學，同時也藉由國際合作的管道，爭取許多額外的資源及開發新的技術。然而在以上的研究成果基礎上，我們重新認識了這個科學問題的複雜度及挑戰性，為了更進一步探討氣膠與雲交互作用之科學問題，本計劃提出完整三年期的規劃，希望單就發展整合觀測技術(著重於衛星觀測與垂直向的光達、無人機及探空氣球觀測)，循序漸進，以對氣膠與雲交互作用做出更好的理解。本計畫設定三個氣膠與雲交互作用的情境劇本進行野地觀測: (1)春季中南半島生質燃燒氣膠與北越層積雲交互作用; (2)夏季南亞生質燃燒與南中國海積雲交互作用; (3)秋冬季北台灣當地污染與中國霾害傳輸氣膠與層狀雲交互作用。以上觀測實驗將配合7-SEAS、CAMPEx及其他相關國際觀測實驗進行，執行高密度氣象垂直剖面觀測，特徵化人為源氣膠與低層層積雲或暖雲之光學及微物理特性，以探討在不同大氣環境與污染條件下，氣膠與雲交互作用下雲微物理變化及對後續降水過程的衝擊。 ;Over the past six years (2012-2017), we have completed a number of concrete results with the support of the Ministry of Science and Technology (MOST), including a total of 31 SCI papers published in relation to Indochinese biomass burning and Chinese haze, and developed a solid methodology for aerosol remote sensing and radiative effect estimation. At the same time, through the pipeline of international cooperation, we have won many additional resources and developed new technologies. However, on the basis of the above research results, we re-understand the complexity and challenge of this scientific problem. In order to further discuss the aerosol-cloud interaction and its subsequent regional climate and hydrology changes, a three-year plan is proposed to the MOST. We hope to develop an integrating observation package (including satellite, lidar, UAV, and sounding observations), step by step, to make a better understanding of this scientific problem. In this project, three scenarios of aerosol-cloud interactions are set up for conducting field observations: (1) the springtime Indochina biomass-burning aerosols vs. cumulus clouds in the North Vietnam; (2) the summertime South Asia biomass-burning aerosols vs. cumulus clouds in the South China Sea; (3) The local and Chinese haze aerosols vs. stratiform clouds in northern Taiwan in autumn and winter. The above observation experiments will be carried out in conjunction with the 7-SEAS, CAMPEx and other relevant international field experiments. We will perform high-density meteorological vertical profiling to characterize the optical and microphysical characteristics of aerosols and clouds, as well as atmospheric state parameters. Our goal is to understand what kind of environment conditions driving aerosol-cloud interaction process, and consequentially how the aerosol-cloud interaction impacts on cloud microphysics, precipitation processes, and regional climate change. |
