Temperature and radiation variations over land with a clear sky typically lead to
A.	temperature reaching a maximum closer to noon than to sunset.
B.	minimum temperature occurring after sunrise.
C.	outgoing terrestrial radiation peaking at noon.

Answer (A) is incorrect.
Peak isolation occurs around noon, but maximum surface air temperature occurs during mid-afternoon.

Answer (B) is correct. (FAA-H-8083-28 Chap 11)
At night, heating is absent, but terrestrial radiation continues cooling the earth’s surface. Cooling continues until shortly after sunrise, when incoming solar radiation once again exceeds outgoing terrestrial radiation. Minimum surface air temperature usually occurs shortly after sunrise.

7.11   TEMPERATURE INVERSIONS
Normally, temperature decreases as altitude increases. A temperature inversion occurs when temperature increases as altitude increases.
Temperature inversions usually result in a stable layer of air.
A temperature inversion often develops near the ground on clear, cool nights when the wind is light.
It is caused by terrestrial radiation.
Temperature and radiation variations over land with a clear sky typically lead to the minimum temperature occurring just after sunrise when the incoming solar radiation is not yet strong enough to offset the terrestrial radiation from the Earth.
Smooth air with restricted visibility is usually found beneath a low-level temperature inversion.
