Simulations of glacial climate and ocean biogeochemistry with the CSIRO Mk3L v1.0

This dataset includes both the physical and biogeochemical output of simulations performed with the CSIRO Mk3L v1.2 Earth System Model under broadly Pre-Industrial (PI; 1950 CE) and Last Glacial Maximum (LGM; 21,000 BCE) climates.
Two simulations using the fully coupled Earth System Model, with atmosphere, ocean and sea-ice components, were undertaken by forcing the model with the boundary conditions of each climate state. The boundary conditions included appropriate greenhouse forcing using CO2 equivalents and orbital parameters.
Climatologies of sea surface temperature, sea surface salinity, and x and y vectors of sea surface wind stresses were produced by both the PI and LGM coupled experiments and were used to force the ocean general circulation model. Additional climatologies of sea ice fractional cover, sea surface wind speeds, and net incident short-wave radiation were important for forcing the biogeochemical model. These climatologies are available.
Also available are the three-dimensional global annual averages of oceanic properties for both PI and LGM climates. These include temperature, salinity, oxygen, apparent oxygen utilisation, dissolved inorganic carbon, alkalinity, calcite saturation state, aragonite saturation state, phosphate and iron concentrations.

本数据集包含使用CSIRO Mk3L v1.2地球系统模型（Earth System Model）在近似前工业时代（PI；公元1950年）与末次盛冰期（LGM；公元前21000年）气候条件下开展的模拟的物理与生物地球化学输出结果。
研究人员通过为模型施加对应气候状态的边界条件，完成了两组包含大气、海洋与海冰模块的完全耦合地球系统模拟，所用边界条件涵盖基于二氧化碳当量的合理温室强迫与轨道参数设置。
前工业时代与末次盛冰期的耦合模拟均生成了海表温度、海表盐度以及海表风应力x、y分量的气候态数据，此类数据被用于驱动海洋环流模式。此外，海冰覆盖率、海表风速与净入射短波辐射的气候态数据同样是驱动生物地球化学模型的关键输入项，所有上述气候态数据均已公开可用。
同时公开可用的还有前工业时代与末次盛冰期气候下的全球海洋三维年平均属性数据，涵盖温度、盐度、溶解氧、表观氧利用度、溶解无机碳、碱度、方解石饱和状态、文石饱和状态、磷酸盐与铁离子浓度。
