Scaling Atmosphere with Resize

[Svm420]

Hello I was wondering what the method was to determine atmosphere height after up sizing kerbin. I see many system resizes do this, but don't really know how they come up wit the height for the atmosphere. Thanks!

Well, the first thing I can come up with would be to say: you doubled Kerbin's radius, go double its atmosphere height too. That would preserve the stock ratio. It'll result in a very tall atmosphere though (the stock atmosphere for Kerbin is incredibly tall for its size, compared to Earth).

The second thing I can come up with is to look up common definitions for "Earth's atmosphere ends at height x" and take that as a reference model. Earth is 11x as large as Kerbin. If you define that Earth's atmosphere ends at, I dunno, 200km, then on a 5x stock scale Kerbin it should be set at 5/11th of 200km to replicate Earth's atmosphere scale (that's about 91km, by the way). For small Kerbins, this results in atmospheres shorter than 70km, though.

I do not think atmosphere scale directly to planet scale otherwise I have 700km atmosphere on 10x kerbin . RSS has an atmosphere height of 130Km. 64K was a height of around ~91Km and kerbin365 a 3.2x rescale has a height of ~80Km. I want to know what they used to adjust atmosphere. Except RSS I know they are shooting for real earth. Hope we can get a more definitive answer there...

P.s. Kerbin atmosphere is so tall because it has a different scale height than earth atmosphere.

Oh, you think that there's some sort of overarching formula that mod authors follow? Nope, there isn't. Each author chooses something they feel is fitting, for their own reasons.

Your best bet would be to approach each author individually and ask them about it.

Oh wow lol. I just had hoped for at least some guide lines or something a bit less arbitrary Guess I'll stick with what I have I just wanted to refine it, and learn something new. Thanks for the heads up very appreciated

Not quite true. GregroxMun gave a guideline in his jumbo 32 thread here.

And by reading that post you get...GregroxMun's choice of something fitting for his own reasons. :]
