The air simply isn’t calm enough for gas layers to form.

Of course the stellar brightness and wind (particles) of the hoststar and the planet’s surface temperature? c/w/ould play a role too. https://en.wikipedia.org/wiki/Atmospheric_escape

Not ammonia nor H or He. Are N2 and CO2 the only gasses which can dominate there? CH4 and O2 aren’t stable without biology replenishing them. Neon or heavier noble gasses, if abundance rations are really weird? Bromine is a gas over 59 C°. Could ammonia be stable under a thick cloud layer?
