Hi MrBragg,
Thank you for your feedback. I've checked the ExoPlaSim data repeatedly and cannot see any error in its calculation of the 4-metre thick ice cap. I'm wondering if perhaps the thicker atmosphere--at 1.324 atmospheres--allows for more efficient heat transfer to the poles, making the poles warmer, despite the faster rotation which would tend to counter that effect.
Because it's relatively thin, I've chosen to depict the ice cap only over the oceans, where the surface should be whitecapped in contrast to the dark oceans. In the land locations, it should not affect the topography at all.
I've reworked the topography (my OCD strikes again, lol), ensuring not to "carve out" my mountains in the desert regions. Using this raw data, I've generated a satellite image of this continent using Arsheesh's tutorial, with clouds:
...and without clouds:
By the way, here is the Koppen diagram that helped me shape topography and route rivers:
Please let me know what you think.
