Yeah, it’s not as simple as the comments suggest.

Temperature change by altitude

I think a good start are those articles: [Athmosphere of Earth](en.wikipedia.org/wiki/Atmosphere_of_Earth], Albedo together with the facts

• the thinner the gas (less atoms per m³), the less temperature it transfers
• athmosphere filters light: which is why we see the sky as blue and why a very clear hot day has a high UV index (though most of the dangerous radiation gets reflected)
• the space in the habitable band around earth is rather warm: 80 - 120°C in direct sun exposure while it’s freezing -120 to -150°C in earths shadow; mainly through infrared radiation
