Axisymmetric GCM simulation results from main simulations presented in Eusebi and Schneider (2026). Each simulation netcdf file has the latitude-sigma profiles for the circulation values (including zonal velocity, meridional velocity, temperature, etc.) for various values of $\phi_0$, the metric of seasonality in the paper. Two datasets are provided: one in which a vertical diffusivity coefficient of 2.0 was used, and one in which a diffusivity coefficient of 5.0 was used. The simulation data was generated by running the FMS script available at https://github.com/ryaneusebi/fms-idealized.
