Climate model results of various COSMOS Miocene experiments in NetCDF format

In this data set we publish the simulated global annual mean sea surface temperature (SST), mixed layer depth (ZMLD), horizontal barotropic streamfunction (PSIUWE), zonal (UKO) and meridional (VKE) velocity in 37 m and 3070 m water depth, respectively, global meridional overturning circulation (GMOC), Atlantic meridional overturning circulation (AMOC) and monthly mean sea-ice concentration over a time period of 100 years retrieved from equilibrium climate simulations for the Miocene ca. 20-10 Myrs ago (MIO). The model data has been utilized in the publication by Huang et al. (2017). The climate data has been produced with COSMOS (ECHAM5/JSBACH/MPIOM/OASIS3), utilized at a resolution of T31 in the atmosphere (19 hybrid sigma-pressure levels) and a resolution of GR30 (bipolar orthogonal curvilinear grid, formal resolution of ~3.0°x1.8°) in the ocean (40 z-coordinate levels). The Miocene model setup is based on the publication of Stärz et al. (2017), including changes in orography, bathymetry, ice sheets, atmospheric CO2 and physical land surface characteristics. This setup has been modified by a regional Weddell Sea bathymetry reconstruction. Details on setup and identifiers of Miocene model simulations can be found in Table 1 of Huang et al. (2017).

本数据集发布了源自约2000万至1000万年前中新世（MIO）平衡气候模拟的100年时长序列数据，涵盖以下模拟变量：模拟的全球年平均海表温度（sea surface temperature, SST）、混合层深度（mixed layer depth, ZMLD）、正压水平流函数（horizontal barotropic streamfunction, PSIUWE）、分别对应37米与3070米水深的纬向（zonal, UKO）流速与经向（meridional, VKE）流速、全球经向翻转环流（global meridional overturning circulation, GMOC）、大西洋经向翻转环流（Atlantic meridional overturning circulation, AMOC），以及月平均海冰浓度。该模式数据已被Huang等人（2017）的研究论文所采用。本气候数据由COSMOS（ECHAM5/JSBACH/MPIOM/OASIS3）模式生成，其中大气模块分辨率为T31（包含19层混合西格玛-气压坐标层），海洋模块分辨率为GR30（双极正交曲线网格，名义分辨率约3.0°×1.8°），共设置40个z坐标层。本次中新世模式配置参考Stärz等人（2017）的研究成果，包含地形、水深、冰盖、大气CO₂浓度以及陆地表面物理特征的调整项。该配置通过威德尔海区域水深重建结果进行了修正。关于中新世模式模拟的配置细节与标识符信息，可参见Huang等人（2017）研究论文的表1。
