A diagnostic study of the variability of the Earth radiation energy budget using satellite observations and numerical simulations

即使规定了相同的辐射强迫，全球气候模型之间对年代际气候变化的预测也存在很大差异，这限制了这些预测在为决策提供指导方面的作用。由于缺乏对云和水汽等关键气候反馈因子的定量了解，存在着很大的气候敏感性不确定性。A-Train卫星等观测计划的进展为多角度诊断大气层顶长波和短波辐射的变化以及与之相关的气候强迫和反馈提供了前所未有的机会。这项研究计划致力于解决这些挑战和机遇，并致力于提高我们对地球辐射能量收支变化的理解。

There is a large discrepancy in the projection of decadal climate change among the global climate models even when identical radiative forcing is prescribed, which limits the usefulness of these projections as to providing guidance for policy-making. The large climate sensitivity uncertainty exists for lack of quantitative understanding of such key climate feedback factors as cloud and water vapor. The advancement of observing programs, such as the A-Train satellites, have provided unprecedented opportunities for diagnosing the variations of the top-of-the-atmosphere longwave and shortwave radiation and associated climate forcing and feedback from multiple angles. This research program addresses these challenges and opportunities and is dedicated to improving our understanding of the variability of the Earth radiation energy budget.
