GMSL experiments: atmosphere and ocean annual mean

<p>The first is the pre-industrial control experiment (picontrol). It employs the Earth&#39;s orbital parameters of 1990 CE, and the atmospheric CO₂&nbsp;level 284.70 ppm and CH₄&nbsp;level 791.60 ppb.</p> <p>The second group (lig126 group) includes three simulations, lig126, lig126sl5m, lig126sl10m. The lig126 experiment, which only considers changes in the Earth&#39;s orbital configuration and greenhouse gas levels, uses the orbital parameters of 126 ka, the atmospheric CO₂&nbsp;level 274.99 ppm, and the atmospheric CH₄&nbsp;level 652.52 ppb. In addition to the orbital parameters and greenhouse gas level, lig126sl5m and lig126sl10m further consider the GMSL rise of 5 and 10 m, respectively.</p> <p>The third group (co₂400 group) includes seven simulations, co₂400, co₂400sl0.625m, co₂400sl1.25m, co₂400sl2.5m, co₂400sl5m, co₂400sl10m and co₂400sl20m. In co₂400, the atmospheric CO₂&nbsp;level is 400 ppm, all other boundary conditions (including orbital parameters, CH₄&nbsp;level, bathymetry, and topography) are identical to the picontrol experiment. Compared to co₂400, we consider GMSL rise of 0.625, 1.25, 2.5, 5, 10, and 20 m in other experiments in this group.</p>
