AI 中文摘要

微波辐射计仪器具备独特能力,可用于研究气态巨行星深层大气中的挥发性元素丰度及热量与质量传输。朱诺号(Juno)的微波辐射计(MWR)实验结果已挑战了关于木星对流层的长期假设,未来土星或冰巨行星任务搭载此类仪器,将同样改写人类对气态巨行星大气的认知。本文概述了微波辐射计用于气态巨行星大气研究的能力,包括各类科学动机与当前知识的综述、系统工程层面可理解的辐射计遥感基础简明阐述,以及对未来仪器设计具说明价值的计算。

英文摘要

Microwave radiometer instruments are uniquely capable of studying volatile element abundances and heat/mass transport within the deep atmospheres of giant planets. The results of the Juno MWR experiment have challenged long-held assumptions regarding Jupiter's troposphere, and the inclusion of such an instrument on future missions to Saturn or the ice giants would similarly re-write our understanding of giant planet atmospheres. We present a high-level summary of the capabilities of microwave radiometers for the study of giant planet atmospheres, including a review of the various scientific motivations and current knowledge, concise statement of the fundamentals of radiometer remote sensing accessible at the systems-engineering level, and calculations which are of illustrative value in the design of future instruments.
