Mars Global Circulation Model simulations with varied orbital parameters and ice sources

This dataset contains simulation output of the global atmospheric state of Mars over a number of periods covering the past 20 million years using the Mars PCM, formerly the Mars Global Circulation Model (GCM), used at the Open University. This output is useful as reference global Martian atmospheres undertaken with varying orbital parameters (obliquity, eccentricity and time of perihelion) and ice sources, focussing on the water cycle.Further details on this dataset can be found in the GCM-ORDO-reference-manual.pdf document.

本数据集包含使用英国开放大学（Open University）研发的火星行星气候模型（Mars PCM，前身为火星全球环流模型（Mars Global Circulation Model, GCM）），对过去2000万年多个时段的火星全球大气状态开展模拟所得到的输出结果。该输出可作为基于不同轨道参数（自转轴倾角、偏心率与近日点时刻）及冰源条件构建的火星全球大气参考数据集，研究核心聚焦于水循环过程。有关本数据集的更多详细信息，请参阅GCM-ORDO-reference-manual.pdf文档。
