The Imaging Science Subsystem onboard the Cassini spacecraft recorded numerous high-quality images of Jupiter and Saturn at various wavelengths, from ultraviolet to near-infrared, during its 20-year mission from 1997 to 2017. Using these images, we have developed global maps of Jupiter and Saturn across multiple wavelengths. These maps reveal the global atmospheric structures of Jupiter and Saturn, offering a comprehensive tool to study the physical and dynamic processes of these atmospheric systems on a global scale. Additionally, these multi-wavelength maps, which probe different pressure levels within the atmospheres, help to explore the vertical structure of these processes. Moreover, global maps at different times enable tracking the movement of dynamic phenomena (e.g., clouds, storms, vortices, eddies, waves, and turbulence), thereby enhancing our understanding of atmospheric dynamics on the giant planets.
在1997年至2017年长达20年的任务期间，卡西尼号航天器上的成像科学子系统在从紫外线到近红外的各种波长下，记录了大量木星和土星的高质量图像。利用这些图像，我们绘制了多个波长下木星和土星的全球地图。这些地图揭示了木星和土星的全球大气结构，为在全球范围内研究这些大气系统的物理和动态过程提供了一个全面的工具。此外，这些探测大气中不同压力水平的多波长地图有助于探索这些过程的垂直结构。而且，不同时间的全球地图能够追踪动态现象（如云层、风暴、漩涡、涡流、波浪和湍流）的移动，从而加深我们对巨行星大气动力学的理解。
