摘要

准确诊断区域大气和地表能量预算对于了解与地球能量失衡(EEI)相关的热吸收空间分布至关重要。本文讨论了利用观测约束数据集对这些预算的关键数量进行一致评估的框架和方法。其中还涉及数据产品中对这些评估有影响的假设。我们利用卫星数据和再分析数据对 2001-2020 年平均区域总能量(TE)和干静态能量(DSE)预算进行了评估。我们首次对第五代欧洲再分析(ERA5)、用于研究和应用的现代回顾分析(MERRA-2)第 2 版和日本 55 年再分析(JRA55)的集合应用了一致的框架。通过产品间传播和物理约束评估,对计算出的预算的不确定性进行了评估。此外,我们还利用 TE 预算来推断地表净能量通量场。结果表明,全球范围的偏差为 1 瓦/平方米,大陆范围的偏差为 5 瓦/平方米,区域范围的偏差约为 15 瓦/平方米。与基于遥感和模型的地表通量数据相比,推断的地表净能量通量显示出较小的大尺度偏差。我们利用 DSE 预算来推断冷凝过程产生的大气绝热加热。与基于观测的降水数据相比,DSE 预算显示出比 TE 预算更大的不确定性(全球范围内 10-15 Wm-2),这反映在基于再分析的场中更大的偏差上。需要继续对大气能量预算进行验证,以记录新的和即将推出的观测产品的进展,并在进行 EEI 研究时了解其局限性。

Assessment of Atmospheric and Surface Energy Budgets Using Observation-Based Data Products

Assessment of Atmospheric and Surface Energy Budgets Using Observation-Based Data Products

Accurate diagnosis of regional atmospheric and surface energy budgets is critical for understanding the spatial distribution of heat uptake associated with the Earth’s energy imbalance (EEI). This contribution discusses frameworks and methods for consistent evaluation of key quantities of those budgets using observationally constrained data sets. It thereby touches upon assumptions made in data products which have implications for these evaluations. We evaluate 2001–2020 average regional total (TE) and dry static energy (DSE) budgets using satellite-based and reanalysis data. For the first time, a consistent framework is applied to the ensemble of the 5th generation European Reanalysis (ERA5), version 2 of modern-era retrospective analysis for research and applications (MERRA-2), and the Japanese 55-year Reanalysis (JRA55). Uncertainties of the computed budgets are assessed through inter-product spread and evaluation of physical constraints. Furthermore, we use the TE budget to infer fields of net surface energy flux. Results indicate biases < 1 W/m2 on the global, < 5 W/m2 on the continental, and ~ 15 W/m2 on the regional scale. Inferred net surface energy fluxes exhibit reduced large-scale biases compared to surface flux data based on remote sensing and models. We use the DSE budget to infer atmospheric diabatic heating from condensational processes. Comparison to observation-based precipitation data indicates larger uncertainties (10–15 Wm−2 globally) in the DSE budget compared to the TE budget, which is reflected by increased spread in reanalysis-based fields. Continued validation efforts of atmospheric energy budgets are needed to document progress in new and upcoming observational products, and to understand their limitations when performing EEI research.
