WebAnswer: The atmospheric pressure as such does not make any difference to the dew point as long as the relative humidity and air temperature remain the same. If, however, the air is compressed, then the actual vapour pressure in the air also increases and the dew point is raised. If you warm or co... WebDew Point Temperature. The dew point temperature, T d, is the temperature to which the air must be cooled to reach saturation, without changing the moisture or air pressure. It measures the actual moisture content of a parcel of air. Saturation occurs when the dew point temperature equals the air temperature.

What is dew point: methods of determination and its significance …

WebThe dew point is a measure of moisture in the air, or more specifically, the temperature at which the air becomes fully saturated with water. The dew point formula relies on environmental data including the relative humidity and ambient air temperature. The dew point temperature will always be lower than or equal to the air temperature.
