How is relative humidity calculated?
Relative humidity is estimated from the difference between dry-bulb and wet-bulb temperatures. A larger difference means drier air and lower relative humidity.
What is the dew point?
The dew point is the temperature at which air becomes saturated and water vapor condenses. It is a direct measure of moisture content in the air.
