空氣污染(PM2.5)和全球暖化在全球的影響已成為現今環境健康與氣候變遷的首要議題，而PM2.5(細懸浮微粒)與熱輻射的監測目前僅以地面測站為主，雖可獲準確且連續性的觀測，但受限於測站點位的限制，及大氣的懸浮微粒具極高的時間和空間分布特性，仍無法滿足完整監測之需求。衛星則具空間分布及範圍寬廣之週期性觀測等優點，如能配合先進遙測技術之整合開發，對於台灣地細懸浮微粒與熱輻射近即時之時、空分布將可有效且準確地掌握。本計畫的目標即為整合先進遙測技術與地面觀測資料於台灣地區近即時PM2.5及地表溫度空間分布之監測，包括新一代高時間解析(每10分鐘)的地球同步衛星向日葵8號(Himawari-8)，以建構大氣環境近即時動態監測系統，提供台灣地區對於不同時間尺度和不同地區PM2.5及熱污染對於人體健康影響之評估探討。本計畫分三年期執行，主要工作項目包括整合多元衛星在高時、空解析觀測資料在大氣污染物及其主要成分與地溫反演模式之建構(第一年)、亞洲地區氣膠種類(沙塵、生質燃燒及人為污染物)曝露度與死亡之相關性探討(第二年)，以及各類PM2.5健康環境標準之探討，以提供相關研究及政府部門在環境參數標準制定之參考與環境健康之預警(第三年)，永續健康環境等學術研究及民生社會三大面向，降低國人公共健康之風險。 ;Air pollution (PM2.5) and global warming are the hot issues caused serious problems in public health and climate change all around the world. Currently, the observations of PM2.5 and thermal flux are primarily provided from ground stations, which are limited by the located points and spatial distribution. Due to the high variance of PM2.5 in spatial and temporal distributions, the point measurements are not satisfied for a regional monitor. On the other, satellite equips with the wide and periodical observation which can well compensate the limitation of stations’ point measurements in providing the comprehensive monitor of PM2.5. Associated with the Asian geostationary satellite (Himawari-8), the objective of this project aims at the integration of multi-satellite observations with the advanced remote sensing technology in providing high spatiotemporal PM2.5 and thermal flux for investigating the impacts of air pollution and thermal environment on public health in Taiwan. Thus the main topics proposed in this project for 3 years include the construction of high spatiotemporal PM2.5 and thermal flux retrieval models in the 1st year, the analysis of associations between types of ambient PM2.5 and under-five and maternal mortality in Asia and Africa (2nd year) and further assessing the impacts of air pollution in different level of exposure and component for the reference of standard air quality of PM2.5 and the sustainable public health in Taiwan during the last year.
