The dew point temperature (Td) of a moist air sample is the temperature to which the sample must be cooled to reach saturation with respect to liquid water.
Dew point temperature (Td) is calculated with the following formula:
Pw is the water vapor pressure (see the separate calculation formula for Pw). The parameters A, m, and Tn depend on the temperature as shown in table NN.
