| 摘要: |
| 穿越地球时空研究计划（Cross Earth System Time and Space，CRESTS计划）将结合模式模拟与古气候资料，对过去130 ka的气候进行研究，以此对气候模式进行校验。太平洋年代际震荡（PDO）与大西洋多年代际震荡（AMO）作为全球年代际变化的主要模态，在全球气候变化研究中具有重要地位。目前已有不少古气候记录用于重建过去500—1000 a以来的PDO和AMO变化。作为CRESTS计划中的年代际气候变率重建的前期调研，汇总了目前已发表的PDO和AMO重建记录（以.xlsx格式存储），对这些记录的经纬度、载体类型、分辨率、指示意义等进行总结，以推动古PDO和AMO的重建研究。收集整理前人用于重建AMO与PDO的109条古气候记录，涉及的载体包括树轮、冰芯、珊瑚、硬海绵、历史文献、湖泊和深海沉积物。其中AMO重建的记录为77条，PDO重建的记录为32条。报告按照时间跨度、时间分辨率和重建内容对收集的记录进行分类整理。此外，还对前人重建结果的不确定性来源进行了总结。 |

| Abstract: |
| The Cross Earth System Time and Space (CRESTS) project, initiated primarily by Chinese scientists, will combine model simulations with paleoclimate data to study the climate of the past 130 ka. The Pacific Decadal Oscillation (PDO) and the Atlantic Multidecadal Oscillation (AMO), as major modes of global decadal variability, play an important role in global climate change research. There are already numerous paleoclimate records used to reconstruct PDO and AMO variations over the past 500—1000 years. This report is a preliminary investigation for the decadal climate variability reconstruction in the CRESTS project. It summarizes the currently published PDO and AMO reconstruction records, including their latitude and longitude, type of proxy, resolution, and indicator significance, to advance the reconstruction research of ancient PDO and AMO. The report gathers and organizes 109 paleoclimate records used for reconstructing AMO and PDO from previous studies. The proxies involved include tree rings, ice cores, corals, sclerosponge, historical documents, lake sediments, and deep-sea sediments. Among these, 77 records are for AMO reconstruction and 32 records are for PDO reconstruction. The report classifies and organizes the collected records based on their time span, temporal resolution, and reconstruction content. Additionally, it summarizes the sources of uncertainty in previous
reconstruction results. |
