Abstract
The datasets for the tier-1 Scenario Model Intercomparison Project (ScenarioMIP) experiments from the Chinese Academy of Sciences (CAS) Flexible Global Ocean-Atmosphere-Land System model, finite-volume version 3 (CAS FGOALS-f3-L) are described in this study. ScenarioMIP is one of the core MIP experiments in phase 6 of the Coupled Model Intercomparison Project (CMIP6). Considering future CO2, CH4, N2O and other gases’ concentrations, as well as land use, the design of ScenarioMIP involves eight pathways, including two tiers (tier-1 and tier-2) of priority. Tier-1 includes four combined Shared Socioeconomic Pathways (SSPs) with radiative forcing, i.e., SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5, in which the globally averaged radiative forcing at the top of the atmosphere around the year 2100 is approximately 2.6, 4.5, 7.0 and 8.5 W m−2, respectively. This study provides an introduction to the ScenarioMIP datasets of this model, such as their storage location, sizes, variables, etc. Preliminary analysis indicates that surface air temperatures will increase by about 1.89°C, 3.07°C, 4.06°C and 5.17°C by around 2100 under these four scenarios, respectively. Meanwhile, some other key climate variables, such as sea-ice extension, precipitation, heat content, and sea level rise, also show significant long-term trends associated with the radiative forcing increases. These datasets will help us understand how the climate will change under different anthropogenic and radiative forcings.
摘要
本文介绍了中国科学院大气物理研究所大气科学和地球流体力学数值模拟国家重点实验室研发的耦合气候系统模式CAS FGOALS-f3-L参与第六阶段耦合模式比较计划(CMIP6)情景模式比较计划(SceanrioMIP)第一级(tier-1)的实验数据集。SceanrioMIP是CMIP6的核心比较计划之一。考虑到未来的CO2、CH4、N2O和其他气体浓度,以及土地利用,SceanrioMIP的设计涉及8条路径,包括两层优先级(tier-1和tier-2)。Tier-1包括四个具有不同辐射强迫的共享社会经济路径(SSPs),即SSP1-2.6、SSP2-4.5、SSP3-7.0和SSP5-8.5,其中2100年前后全球大气顶部平均辐射强迫分别约为2.6、4.5、7.0和8.5 W m−2。本研究对CAS FGOALS-f3-L的ScenarioMIP数据集进行了介绍,如存储位置、大小、变量等。初步分析表明,这四种情景下,到2100年前后地表气温将分别升高约1.89℃、3.07℃、4.06℃和5.17℃。与此同时,其他一些关键的气候变量,如海冰面积、降水、海水热含量和海平面上升高度,也显示出与辐射强迫增加有关的显著的长期趋势。这些数据集将帮助我们了解在不同的人为和辐射强迫作用下气候将如何变化。
