从月平均云发生频率（COF）的垂直分布和纬向分布的角度对多传感器云高度观测进行了研究和比较。本研究虽然强调了标准的多角度成像光谱仪（MISR）云顶高度（CTH）检索，但也讨论了不同被动和主动遥感技术在云探测和高度评估方面的优缺点。与大气红外探测器（AIRS）、云气溶胶激光雷达和红外探路者卫星观测（CALIPSO）相比，标准MISR CTH检索对高薄卷云的灵敏度较低，但与其他被动传感器相比，MISR在对流层中下层提供了更精确的CTH检索，特别是对于行星边界层中的云。
Multi‐sensor cloud height observations are investigated and compared in terms of vertical and latitudinal distributions of monthly mean cloud occurrence frequency (COF). Although this study emphasizes the standard Multiangle Imaging SpectroRadiometer (MISR) cloud top height (CTH) retrieval, the strengths and weakness among different passive and active remote sensing techniques with respect to cloud detection and height assessment are also discussed. The standard MISR CTH retrieval is less sensitive to high thin cirrus than the Atmospheric Infrared Sounder (AIRS) and Cloud‐Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO), but MISR provides more accurate CTH retrievals in the middle and lower troposphere compared with other passive sensors, especially for clouds in the planetary boundary layer.
