    A number of these actually are taken into account during the simulation. Solar flux (and star temp), albedo of different land types, vegetation cover, obliquity / eccentricity, and gas concentrations / pressures are all treated. There are certainly simplifications and systematic errors in the model outputs, but in terms of variables that get treated it does quite a thorough job and allows the effects of any one of these variables to be isolated and varied.

    Nice then could be an alteration of those parameters that gives abnormal temperatures on continents like I read before?

    When I ran the simulation for Rheia I kept all of the parameters identical to Earth's except for the heightmap. ExoPlaSim consistently seems to overestimate temperatures--it does so by several degrees for Nikolai's baseline earth model--and I had to drop the CO2 levels by >50% to get more reasonable temperatures for my simulations. I could do that here, too, though Tiluchi seems to have already done a really nice job of hybridizing the ExoPlaSim results with their intuition.
