The NASA C1440-LLC2160 dataset is the simulation output from research into coupling two models: a global atmospheric model and a global ocean model that were originally designed to be run separately. The atmospheric model is a C1440 configuration of the Goddard Earth Observing System (GEOS) atmospheric model running on a cubed-sphere grid. The global ocean model is an LLC2160 configuration of the MITgcm model that uses a latlon-cap grid. Each model was run for over 10000 hourly timesteps covering over 14 simulation months. With more than 10000 time steps and multiple scalar fields, it totals approximately 1.8 PB.
In order to make this dataset more accessible and easier to visualize, the National Science Data Fabric has processed the raw data into the ViSUS data format using their OpenViSUS toolsuite.
It will be used in the 2026 IEEE SciVis Contest to demonstrate cutting-edge technologies for working with petascale climate data provided by NASA.
