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.
