Moving forward - I've done a quick climate sketch and a (rough) height map for input into Climate sim. If it returns something drastically different, I'll input the new values later.
Height is in 1000m increments.
For the climate sketch, White is ice caps, dark green is dense forest, tan is desert, black are mountains, the rest is mostly grassy lands, with some less dense forest
Hi Ottehcnor,
I admire your hard work and your accomplishment of finalizing your topography. The continent shapes look realistic and I'm looking forward to seeing the full simulation on Clima-Sim. My curiosity: Are you going to be using Earthlike parameters or setting your very own?

Using the demo version of ClimaSim, I can't mess with too many parameters, but theoretically, here are the changes from earth:
Eccentricity = 0.1, so significantly higher than earth
Semimajor Axis = .86 AU (but it's orbiting a star that is only 0.91 solar masses, so in terms of effect on climate this comes close to a wash, plus I couldn't see a place to change the solar parameters, at least in the demo version)
Day length = 22 hours, but again I can't adjust that in the Demo version
CO2 partial pressure is equal to earth
Axial tilt, I left the same, but I may play around with that some more if I don't like the result
All of this resulted in a slightly higher average global temperature at 19.44 C (I think), which is almost exactly what I calculated after accounting for the SMA and Solar density difference (292.48 K ~ 19.3 C), so I'm not too concerned about leaving the number at 1 AU for the SMA for the purpose of the simulation.
That said, here are the next round of maps:
January Temperatures
July Temperatures
Currents
Apologies for a lack of a legend - temperatures are in 5C segments with the hottest in January being above 45C and the coldest being below -25C.

Two new updates - the first, I've gone back over most of the island chains to make the island shapes less regular and simulate erosion, changes in sea level, and the like, resulting in a map with islands I like a little better:
Plus, I've also mapped out the next step in climate work, Thermal Equators, ITCZs, and High-pressure zones for
January:
and July:
Feedback is appreciated, suggestions for improvement are welcome, questions will be answered in as timely a manner as I can manage.
Looking good so far! Excited to see what this looks like with more detail. Just a heads-up that you might want to mix up your island coastlines a bit- I see upside-down Java and Nusa Tenggara in the northeast quadrant, and backwards Puerto Rico in the northwest quadrant. Guessing those are something like placeholders, but it definitely made me do a double-take.
Good eye! Most of the islands used real-world island chains as a reference. Each time I tried to do the islands without a reference, they ended up looking too regular. Most of the islands are so small that any distinctive features from their reference are distorted enough. But for the larger islands with fewer distortions (Java, Puerto Rico, etc.), that's a good place to make some intentional changes.
Added the winds - a few spots where it looks a little weird, but unless there is a major problem, I think this will do for mapping precipitation. I also changed a few of the islands again.
January Wind
July Wind
Let me know if there are any glaring problems, but if not I will hopefully move on to precipitation by next weekend.
