Assuming a dry adiabatic lapse rate of 5.4 *F/1000 feet indicates the temperature of the sky is being measured at an altitude of 8,700 feet AGL, or 11,000 feet MSL.

Ground and Sky Thermal Observation for NearSys Station, 12 September 2017
The temperature of the ground and sky was recorded at 5:50 AM today. The ground had a temperature of 38 *F and the sky a temperature of -9 *F. That's a difference of 47 *F. The sky was overcast with light cirrus. The cirrus was just thick enough to create a halo around the waning gibbous moon.
