了解云的特性，如云顶高度(Cth)，对于了解它们对地球辐射收支和气候变化的影响至关重要。来自大气红外探测仪(AIRS)的高光谱分辨率测量非常适合于揭示关于云高度的有价值的信息。将从AIRS单视场(FOV)辐射测量得到的Cth反演与运行中的MODIS(中分辨率成像光谱仪)云产品以及从EOS(地球观测系统)CloudSat和CALIPSO(云气溶胶激光雷达和红外探路器卫星观测)卫星上的雷达和激光雷达获得的2级产品进行了比较。研究了两种不同云条件下的情况，并讨论了红外探测辐射的CTH产品的优缺点。
Knowledge of cloud properties like cloud top height (CTH) is essential to understand their impact on the earth's radiation budget and on climate change. High spectral resolution measurements from the Atmospheric Infrared Sounder (AIRS) are well suited to reveal valuable information about cloud altitude. The CTH retrievals derived from AIRS single field‐of‐view (FOV) radiance measurements are compared with the operational MODIS (Moderate Resolution Imaging Spectroradiometer) cloud product, and Level 2 products obtained from radar and lidar instruments onboard the EOS (Earth Observing System) CloudSat and the CALIPSO (Cloud‐Aerosol Lidar and Infrared Pathfinder Satellite Observation) satellites. Two cases containing a variety of cloud conditions have been studied, and the strengths/shortcomings of CTH products from infrared (IR) sounder radiances are discussed.
