World Climate Lab

In short, I do recommend it. But I'm not going to strictly say it's for everyone. You have to do know what you want to do with it, and what kind of data it outputs. It is quite well done, and much faster and more fine grained as far as I can tell than CPU sims like exoplasim. It's also FAR easier to setup, and the dev is super responsive to feature requests! Rather than rattle on, I'm going to attach a simple webpage describing my findings of my Kerbal Space Program mod's (RDK) version of the beloved Kerbal homeworld of Kerbin: https://glacialsoftware.net/RDKKerbinReport/ PS: BTW, I am the author of the KSP mod Kopernicus if anyone is wondering.

I am really enjoying how well this tool is able to take a heightmap and estimate a climatological model. The wind and ocean currents were especially exciting to watch their animations. There is room to grow (e.g., controlling the output image resolution, using the mouse to rotate the globe, exporting the satellite image with or without clouds, a strange simulation bias around the equator), but it has started off its early access very strongly. I am very happy to use this with my heightmaps to play with climatological modeling and planning.

with how early it is in its release phase, this tool is super incredible, i am especially impressed with the depth of its climate simulation for non-earth-like worlds. would love to see a custom biome system maker tool in the future or something like that, but i can tell this is on the track to greatness! excellent work

This is going to do numbers as a worldbuilding tool I'm sure, it's very in depth and gorgeous to boot. I've personally always really been a fan of the specific retro orange on black look so this is like eye candy to me. Settings and tutorial are all clearly explained, only issue I had was not understanding I had to change the water mask when uploading a new heightmap at first. I really like the slow rotator and tidally locked custom biome classifications, both and slow rotators especially so seem very overlooked in planetbuilding and deserve the distinction. Some things I might like to see in the future are zooming on maps, better true binary planet representation, and along with that large tidal ranges, biome colours could match better in legend vs map (or maybe outline that biome while mousing over it in legend?), and better polar coordinate resolution. Overall very solid foundation and look forward to where it will go, a great tool for the serious planetbuilder who isn't great at running niche self-setup climate programs themselves.

Can't believe how incredible this program is already just as a foundation for what's being built on top of it! Dev has already listened to users and implemented improvements. Very, very excited for the full version later down the line, and already having a ton of fun with it as it is.
