[1]在热带针状物和卷云层的卷云区域研究-佛罗里达地区卷云实验期间，中分辨率成像光谱仪(MODIS)机载模拟器(MAS)和太阳光谱通量辐射计(SSFR)在同一架飞机上运行，NASA ER-2。MAS提供了云光学厚度和有效冰粒半径的二维水平场，而SSFR测量了可见光到近红外波长范围(0.31.7μm)的光谱辐照度。MAS反演以及同一飞机上的雷达/激光雷达组合系统的垂直剖面被用来构建三维云场，并将其输入蒙特卡罗辐射传输模型。将模拟的光谱反照率(反射上升流与入射下降流辐照度之比)与SSFR实测值进行了比较。对于两种情况，研究了空间云不均匀、单次散射参数的不同近似、垂直结构、卷云光学厚度和冰晶有效半径的相对重要性。
[1] During the Cirrus Regional Study of Tropical Anvils and Cirrus Layers–Florida Area Cirrus Experiment, the Moderate Resolution Imaging Spectroradiometer (MODIS) airborne simulator (MAS) and the solar spectral flux radiometer (SSFR) operated on the same aircraft, the NASA ER-2. While MAS provided two-dimensional horizontal fields of cloud optical thickness and effective ice particle radius, the SSFR measured spectral irradiance in the visible to near-infrared wavelength range (0.3–1.7 μm). The MAS retrievals, along with vertical profiles from a combined radar/lidar system on board the same aircraft were used to construct three-dimensional cloud fields, which were input into Monte Carlo radiative transfer models. The simulated field of spectral albedo (ratio of reflected upwelling to incident downwelling irradiance) was compared with the SSFR measurements. For two cases, the relative importance of spatial cloud heterogeneities, various approximations of the single scattering parameters, vertical structure, cirrus optical thickness, and ice crystal effective radius was studied.
