Earth's atmosphere, as you probably know, is divided into five layers - the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
How can I determine plausible altitudes for the boundaries of these layers for my Earth-like planet's atmosphere? I have already figured out the atmosphere's composition, pressure*, density*, and escape velocity, and I know other possibly relevant things about the planet such as mass, radius, gravity, density, surface temperature, albedo, axial tilt, orbit etc.
Are these values necessary? If so, are there any I need and don't have? Also, a couple clarifications:
I'm not necessarily looking for an empirical, universal method to precisely determine the exact figures, I just need a way to give me reasonable results,
I know that something like layers of the atmosphere might seem insignificant for worldbuilding, but I am interested in knowing this for my planet, and so I'd rather not just handwave it entirely.
*at any altitude; I have a calculator for that.
EDIT: As per Morris The Cat's request, I've shared the values regarding the planet and atmosphere. Here they are:
Mass – 1.2x Earth
Radius – 1.17x Earth
Gravity – 0.88x Earth
Density – 0.75x Earth
Semi-major axis – 0.92 AU
Eccentricity – 1.8x Earth
Periapsis – 0.89 AU
Apoapsis – 0.95 AU
Year – 0.8x Earth, 294 Earth days
Orbital velocity – 1.14x Earth
Axial tilt – 1.17x Earth
Albedo – 1.22x Earth
Escape velocity – 1.01x Earth
Atmosphere – 71.9% N, 25% O2, 1.95% Ar, 1.1% CO2, 0.05% trace gases
Atm. pressure @ sea level – 1.45 atm
Air density @ sea level – 1.7x Earth
Specifically I've compared them to Earth's corresponding values which I thought were most fit for what the comment suggested.
