Is sky-glow affected by height? I'm an architecture student and my graduation project will consist of building a research center for outer space, my question is whether or not height would affect sky-glow or not ? Thanks in advance, any help is appreciated.
Sky-glow is a generic term for the diffuse light not due to the sun, moon or stars (or aurorae, I suppose). Much of it is light pollution from the ground, some is the zodiacal light from dust in space, and the coolest part may arguably be the air-glow from chemical reactions in the upper atmosphere.
So, depending on height the different components would change strength. Urban light pollution apparently declines as $\propto d^{-2.5}$ (&quot;Walker's law&quot;) due to spreading and absorption, so it would decline with altitude. The zodiacal light would get stronger with less absorption in the atmosphere. The air glow is altitude-dependent, and would presumably intensify at first, until one is above it (like the ISS) is.
