| 1 | 多角度成像光谱辐射仪在大气污染研究中的应用回顾显示文摘美国宇航局于1999年底发射的多角度辐射成像光谱仪(MISR)采用了独特的多角度观测设计,将9台相机沿卫星航迹方向按照固定角度排列并同时采集反射光.这种设计使其具备了当前其他星载气溶胶遥感设备不具备的在陆地和海洋上空反演包括气溶胶浓度、形状以及组分的多种特性的能力.由于对细颗粒物非常敏感,MISR为研究区域颗粒物空气质量的时空分布特性提供了新的数据来源.首先简要介绍MISR设备、它的气溶胶反演算法及数据结构,然后综合论述了目前MISR气溶胶数据在空气质量研究方面的应用状况包括在污染事件(例如沙尘、火灾以及城市空气污染)中对颗粒物空间分布的观测.MISR高质量的气溶胶数据可以作为颗粒物浓度的定量指标,回顾了目前在估算地面颗粒物浓度方面的研究成果,介绍了使用MISR高级数据对烟尘高度以及颗粒物成份的研究.由于中分辨率成像光谱仪(MODIS)的气溶胶数据在中国有较广泛的使用,讨论中尽可能的与之进行了比较.最后总结了MISR数据在空气质量研究中的优点与不足.相信MISR反演的丰富的高度定量化的气溶胶数据对研究中国空气质量问题具有很大的应用价值. | 刘阳 陈丹 Ralph A.Kahn 贺克斌 | 2008 | 中国科学(D辑)2008，38，3： | 2 |

| 5 | Review of the applications of Multiangle Imaging SpectroRadiometer to air quality research显示文摘The Multiangle Imaging SpectroRadiometer(MISR) launched by NASA in late 1999 has a unique mul-tiangle design,which points nine cameras at fixed angles along the satellite flight track and collects reflected solar radiation simultaneously.This design allows the retrieval of a rich dataset of particle abundance,shape and composition over both land and ocean.Some of its capabilities have not been seen by any currently operating satellite aerosol sensors.Since MISR is sensitive to fine particles,it provides a new data source to study the spatial and temporal characteristics of air quality over large geographical regions.We first briefly introduce the MISR instrument,the retrieval and structure of MISR aerosol data,and then review the applications of MISR aerosol data in various aspects of air quality research since its launch.These include the spatial distributions of particle pollution events such as dust storms,wild fires,and urban pollution.Because of the high quality of MISR aerosol data,they can be used as quantitative indicators of particle pollution levels.We review the current modeling studies of surface level particle concentrations.Next,we introduce research results using MISR's advanced data such as the plume heights,and particle microphysical properties.In the discussion,we compare MISR research with current MODIS research to the best of our ability as MODIS data have been more extensively explored by the Chinese scientific community.Finally,we summarize the advantages and disadvantages of MISR data related to its applications to the air quality research.Given the highly quantitative measurements and comprehensive aerosol information MISR can provide,we believe that it will provide great values to advance our understanding of the particle air pollution in China. | Ralph A.KAHN | 2009 | Science China Earth Sciences2009，52，1： | 0 |
