Spatially Inhomogeneous Cirrus: Influence on Atmospheric Radiation

非均匀卷云场的辐射效应将通过航空测量(辐射和微物理特性)、三维(3D)辐射传输模式和动态云分辨卷云模式相结合来研究。一架仪表化飞机(李尔喷气式飞机)将在野外活动中对卷云上方的光谱辐射进行采样。根据这些数据，将恢复卷云的微物理特性，并将其与安装在李尔喷气式飞机下方的飞机拖曳的传感器航天飞机收集的同时现场测量进行比较。在紧密搭配下，成像数字CCD相机将观测到采样卷云区域的空间不均匀性。同时，云分辨模式将模拟微物理卷云场。结合现场测量和反演的微物理卷云场以及模拟的微物理卷云场将被用作三维辐射传输模式的输入，以研究空间不均匀卷云的辐射效应。

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.
