Equations to Calculate Dew Point from Wet-bulb

In the above equation, T is the temperature in °C, Wb is the wet-bulb temperature in °C, Psta is the station pressure in millibars, ew is vapor pressure related to the wet-bulb temperature in millibars, e is the actual vapor pressure in millibars, and Td is the dew point in °C.
