what is the dewpoint temperature
Dew point is a measure of atmospheric moisture. It is the temperature to which air must be cooled to reach saturation (assuming air pressure and moisture content are constant). A higher dew point indicates more moisture present in the air.It is sometimes referred to as dew point temperature, and sometimes written as one word (dewpoint).n simpler terms: the dew point, or frost point, is the temperature at which dew or frost will form should the air temperature fall sufficiently.
