Small orbital forcing changes alter the ocean circulation of Earth's next future supercontinent: Simulations

This dataset contains the simulations from the manuscript "Small orbital forcing changes alter the ocean circulation of Earth's next future supercontinent".

From the methods section of the manuscript:
The simulations are carried out using the fully-coupled ocean-atmosphere general circulation model ROCKE-3D version Planet 1.0 (R3D1) (Way et al., 2017). The model is run at a horizontal resolution of 4 x 5 degrees and simulations were integrated for 5000 and 7000 years for PD and future forcing, respectively, to ensure they were in equilibrium. The topography and bathymetry is the one used by Way et al. (2021) in their simulation 2 (Aurica). This includes a fully dynamic ocean 4252 m deep and land elevations close to present day mean topography and elevations between 1 and 858 m.
Due to high uncertainties in its future evolution, atmospheric composition is kept constant at year 1850 levels, following the setup in Way et al. (2021): the atmosphere is dominated by nitrogen with 21% oxygen, 285 ppmv CO2, 0.3 ppmv N2O and 0.79 ppmv CH4, and no aerosols or ozone are included.
Two simulations are presented: PD_Aurica which which has present-day day-length (24 hrs) and insolation (1361 Wm-2) and F_Aurica where we apply orbital forcing consistent with 250 Ma into the future - day length is increased by 0.5 hrs and insolation is increased by 2.6 Wm-2 (see Way et al., 2021). 

PD_Aurica corresponds to the output files with the following names: ANN4500-4999.*F_AURICA_RAND_PD_03.nc
F_Aurica corresponds to the output files with the following names: ANN6500-6999.*F_AURICA_RAND_PD_01.nc

The diagnostic files including AGC, AIJ, AIJK and AIJL in the filename contain atmospheric diagnostics and outputs, whereas those that include OIJ, OIJL, OJL and OTJ contain ocean diagnostics and outputs.
