Earth lapse rate
WebUnder these conditions, when unsaturated air rises and expands, the temperature decreases at the dry adiabatic lapse rate (9.8 °C per kilometre, or roughly 23 °F per mile) throughout most of the boundary layer. Near Earth’s heated surface, air temperature decreases superadiabatically (at a lapse rate greater than the dry adiabatic lapse rate). Web8.8: Adiabatic Lapse Rate. Earth’s atmosphere is not, of course, isothermal. The temperature decreases with height. The temperature lapse rate in an atmosphere is the rate of decrease of temperature with height; that is to say, it is −dT/dz. An adiabatic atmosphere is one in which P /ρ γ does not vary with height.

Since the temperature decreases in this layer, we subtract 115.2 °F from the temperature at 2640 ft to get the temperature at our desired altitude. 59 - 115.2 = -56.2 °F. Temperature at 35000 feet : -56.2 °F.
