CMIP5/CIMP6(地表2m气温)(5 种模式, 4 种排放情景)
收藏资源简介:
数据包括了中国区域CMIP5计划中的5个模型(GFDL-ESM2M, HadGEM2-ESM-ES, IPSL-CM5A-LR, MIROC5,NorESM-M),4套未来情景下(RCP26, RCP45, RCP60, RCP85)的地表2m气温数据,区域气候模式(Regional Climate Model, RCM)其相对 GCM 具有更高的分辨率,能更好反映区域气候特征。通过 RegCM4 模式动力降尺度方法将中国区域 CMIP5 计划中的5个模型的粗分辨率的 4 套未来情景气候资料降到 0.25 度,再结合 MicroMet 统计降尺度方法将 0.25 度未来气候资料制备成 0.05 度, 逐3小时。
This dataset contains 2-meter surface air temperature data under four future Representative Concentration Pathway (RCP) scenarios (RCP26, RCP45, RCP60, RCP85) from five models (GFDL-ESM2M, HadGEM2-ESM-ES, IPSL-CM5A-LR, MIROC5, NorESM-M) of the CMIP5 (Coupled Model Intercomparison Project Phase 5) project over China. Regional Climate Models (RCMs) exhibit higher spatial resolution than Global Climate Models (GCMs) and can better characterize regional climate features. The coarse-resolution future climate data under the four scenarios from the five CMIP5 models over China were first dynamically downscaled to a 0.25° grid using the RegCM4 model. Subsequently, the 0.25° future climate data were further downscaled to a 0.05° grid with 3-hourly temporal resolution via the MicroMet statistical downscaling method.
