全球高分辨率模拟近海洋表层气温-降水-海温数据集（1990-2020）

1990-2020年全球高分辨率模拟近海洋表层气温-降水-海温数据集来源于最新CMIP6计划。CMIP6是世界气候研究项目（WCRP）组织的第六次气候模式比较计划。原始数据来源于https://www.wcrp-climate.org/wgcm-cmip/wgcm-cmip6。该数据集中包含了全球近海洋表层气温（tmp）、降水（pr）和海温（tos）数据。其中气温和降水数据包含CMIP6中情景模式比较子计划（ScenarioMIP）的4种不同实验场景的共享经济路径(shared socioeconomic pathway, SSP)与辐射强迫(representative concentration pathway, RCP)的矩形组合。(1) SSP126: 在SSP1（低强迫情景）基础上对RCP2.6情景的升级 (辐射强迫在2100年达到2.6W/m2)。(2) SSP245: 在SSP2（中等强迫情景）基础上对RCP4.5情景的升级 (辐射强迫在2100年达到4.5 W/m2)。(3) SSP370: 在SSP3（中等强迫情景）基础上新增的RCP7.0排放路径 (辐射强迫在2100年达到7.0 W/m2)。(4) SSP585: 在SSP5（高强迫情景）基础上对RCP8.5情景的升级(SSP585是唯一能使辐射强迫在2100年达到8.5 W/m2的SSP场景)。海温数据提供SSP126情景数据。

The global high-resolution simulated near-surface ocean air temperature-precipitation-sea surface temperature dataset spanning 1990–2020 is sourced from the latest Coupled Model Intercomparison Project Phase 6 (CMIP6) initiative. CMIP6 is the sixth phase of the Coupled Model Intercomparison Plan organized by the World Climate Research Programme (WCRP). The original data is obtained from https://www.wcrp-climate.org/wgcm-cmip/wgcm-cmip6.
This dataset contains global near-surface ocean air temperature (tmp), precipitation (pr), and sea surface temperature (tos) data. Among them, the air temperature and precipitation data cover the rectangular combinations of Shared Socioeconomic Pathways (SSPs) and Representative Concentration Pathways (RCPs) from four different experimental scenarios under the Scenario Model Intercomparison Project (ScenarioMIP) of CMIP6:
1. SSP126: An upgrade of the RCP2.6 scenario based on SSP1 (low-forcing scenario), with radiative forcing reaching 2.6 W/m² by 2100.
2. SSP245: An upgrade of the RCP4.5 scenario based on SSP2 (medium-forcing scenario), with radiative forcing reaching 4.5 W/m² by 2100.
3. SSP370: A newly added RCP7.0 emission pathway based on SSP3 (medium-forcing scenario), with radiative forcing reaching 7.0 W/m² by 2100.
4. SSP585: An upgrade of the RCP8.5 scenario based on SSP5 (high-forcing scenario). SSP585 is the only SSP scenario that enables radiative forcing to reach 8.5 W/m² by 2100.
The sea surface temperature data is provided for the SSP126 scenario.
