Earth’s Mantle Convection

The dataset, generated from a scientific simulation, consists of a time series (251 steps) of 3D scalar fields on a spherical 180x201x360 grid covering 500 Myr of geological time. Each time step is 2 Myrs, and the fields are:

• temperature [degrees K],
• three Cartesian velocity components [m/s],
• thermal conductivity anomaly [Watt/m/K],
• thermal expansivity anomaly [1/K],
• temperature anomaly [degrees K], and
• spin transition-induced density anomaly [kg/m^3].

The simulation was performed in double precision, however, to reduce downloading time, we provide the data in single precision. Each file was saved in a NetCDF Climate and Forecast (CF) convention format, with each 3D scalar field being a function of latitude [degrees north], longitude [degrees east], and radius [km]. The model’s inner and outer radii are 3485 km and 6371 km, respectively.
