| Abstract (English): | The study of shortwave (SW) radiation and its interactions with our planet has proven critical for advancing the understanding of the Earth–atmosphere system. Here, the author shares an accessible and high-level perspective on recent progress, surprises encountered, and promising future research directionsa. A brief context for the study of SW radiation is provided, after which three specific aspects are focused upon that the author considers particularly important. First, the significance of three-dimensional (3D) SW radiative effects is highlighted via impacts on surface downward SW radiation in complex cloud fields. Crucially, it is shown that probability distributions of surface radiation can only be reliably simulated when accounting for 3D effects, which has implications for various applications and next-generation atmospheric modeling. Second, the significance of the often overlooked diurnal cycle in global top-of-atmosphere upward SW radiation is underscored by quantifying the controlling properties and processes. Opportunities for improved future satellite observations of the global diurnal cycle are noted. Third, the wealth of information provided by the spectral dimension of SW radiation is demonstrated through the extraction and attribution of SW spectral signatures. It is argued that further exploration of the spectral dimension, aided by the recently launched and upcoming suite of spectrally resolved SW satellite observations, promises a new era of SW radiation research.

| Abstract (Chinese): | 摘要: 广泛的研究已表明短波辐射及其与地球相互作用对于更好地理解地球大气系统至关重要。 本文作者以通俗易懂的视角, 分享了近期研究进展、意外发现以及未来研究方向的展望。 本文简要介绍了短波辐射的研究背景, 并重点阐述了作者认为尤为重要的三个方面。 首先, 通过考虑复杂云分布情况之下地面向下短波辐射的影响, 强调了三维短波辐射效应的重要性; 特别是, 只有考虑三维辐射效应才能可靠地模拟地表辐射的概率分布, 这对各种研究应用以及下一代大气模式都有重要意义。 其次, 通过量化控制属性和过程, 强调了全球大气顶部向上短波辐射中经常被忽视的日变化特征的重要性, 并指出可以改进卫星观测来提升对全球短波辐射日变化的研究。 第三, 通过提取和归因短波光谱特征, 本文展示了短波辐射光谱维度所提供的丰富信息。 本文认为, 在最近发射和即将发射的光谱分辨率短波卫星观测的帮助下, 对短波辐射光谱维度的进一步探索有望开启短波辐射研究的新时代。 [ABSTRACT FROM AUTHOR] |
