GCM output (diagfi) from Early Mars simulation without ocean heat transport (NOHT)

This dataset contains the diagfi output file from a 3D Global Climate Model (Generic-PCM ) simulation of early Mars performed without ocean heat transport (OHT disabled). The simulation explores early Mars surface and atmospheric conditions under a dense CO₂–H₂ atmosphere, consistent with scenarios proposed to allow transient liquid water. In this configuration, ocean-covered grid cells are still thermodynamically coupled to the atmosphere via a slab ocean representation, but no lateral ocean heat transport is permitted. This setup isolates the role of the atmosphere in redistributing heat and serves as a control experiment for assessing the climatic impact of ocean dynamics.
