The radiative effects of inhomogeneous cirrus fields will be studied by a combination of airborne measurements (radiation and microphysical properties), a three-dimensional (3D) radiative transfer model and a dynamic cloud-resolving cirrus model. An instrumented aircraft (Lear-Jet) will sample spectral radiation above cirrus within a field campaign. From these data the microphysical cirrus properties will be retrieved and compared to simultaneous in situ measurements collected with an aircraft-towed sensor shuttle which is mounted below the Lear-Jet. In close collocation the spatial inhomogeneities of the sampled cirrus fields will be observed by an imaging digital CCD camera. In parallel, a cloud-resolving model will simulate microphysical cirrus fields. The combined in situ measured and retrieved microphysical cirrus fields as well as the simulated microphysical cirrus fields will be used as input to a 3D radiative transfer model to investigate the radiative effects of spatially inhomogeneous cirrus.

将结合空中测量（辐射和微物理特性）、三维（3D）辐射传输模型和动态云分辨卷云模型来研究不均匀卷云场的辐射效应。一架装有仪器的飞机（Lear-Jet）将在实地活动中对卷云上方的光谱辐射进行采样。从这些数据的微物理卷云特性将被检索和比较，同时在现场测量收集的飞机拖曳传感器航天飞机安装在下面的里尔喷气。在密切配合的采样卷云场的空间不均匀性将被观察到的成像数字CCD相机。同时，一个云解析模式将模拟微物理卷云场。结合在现场测量和检索的微物理卷云场以及模拟的微物理卷云场将被用作输入到一个三维辐射传输模式，调查空间不均匀卷云的辐射效应。
