A.
Air temperature
B.
Saturation vapour pressure
C.
Relative humidity
D.
Dew point temperature
AnswerAnswer: Option D

Dew point is a good indicator of the air's actual water vapour content, unlike relative humidity, which takes the air's temperature into account. High dew point indicates high water vapour content; low dew point indicates low water vapour content.
