不同SSP情景下全球近地表气温和降水后处理集成产品(2046-2065)
收藏资源简介:
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。该数据集包含了CMIP6中情景模式比较子计划(ScenarioMIP)的4种SSP情景组合。(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)。 利用GRU数据对原始CMIP数据进行后处理偏差校正得到2046-2065年月尺度降水(pr)和气温(tas)预估后处理数据集, 参考期为1985-2014年。
CMIP6 is the 6th phase of the Coupled Model Intercomparison Project (CMIP) organized by the World Climate Research Programme (WCRP). The raw data is sourced from https://www.wcrp-climate.org/wgcm-cmip/wgcm-cmip6. This dataset includes four SSP scenario combinations under the Scenario Model Intercomparison Sub-Project (ScenarioMIP) of CMIP6: 1. SSP126: An upgraded version of the RCP2.6 scenario based on SSP1 (low-forcing scenario), with radiative forcing reaching 2.6 W/m² by 2100. 2. SSP245: An upgraded version 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 upgraded version of the RCP8.5 scenario based on SSP5 (high-forcing scenario); SSP585 is the only SSP scenario that allows radiative forcing to reach 8.5 W/m² by 2100. The post-processed dataset of monthly-scale precipitation (pr) and air temperature (tas) projections for 2046–2065 is obtained by performing bias correction on the raw CMIP data using GRU, with the reference period set as 1985–2014.
