卷云的热辐射，光谱分辨率在100-1400 cm−1范围（100-7.1 μm），已被建模，并与在意大利阿尔卑斯山3480 m高度的Testa Grigia地面站进行的两次实地活动期间进行的测量进行了比较。通过光谱拟合对卷云微观物理学的分析表明，在667 cm−1二氧化碳吸收带以下的波数处使用远红外部分的重要性，由于强水汽吸收导致大气高度不透明，只有少数测量存在。拟合得到的云参数分布与中纬度卷云参数的典型统计分布符合得很好。
The thermal emission of cirrus clouds, spectrally resolved in the 100–1400 cm−1 range (100–7.1 μm), has been modeled and compared with measurements performed during two field campaigns from the ground‐based site of Testa Grigia on the Italian Alps at 3480 m of altitude. The analysis of cirrus microphysics, through spectral fitting, shows the importance of using also the far infrared portion of the emitted spectrum at wave numbers below the 667 cm−1 carbon dioxide absorption band, where only a few measurements exist because of the high opacity of the atmosphere caused by the strong water vapor absorption. The resulted distribution of the fitted cloud parameters is in good agreement with the typical statistical distribution of the midlatitude cirrus cloud parameters.
