Relative Humidity

Introduction to Relative Humidity

Relative Humidity is the ratio of actual vapor pressure to the saturated vapor pressure at a given temperature. This parameter is used in meteorology to measure the amount of moisture in the air compared to the maximum amount of moisture the air can hold at that temperature.

Parameter usage:

• actualVaporPressure= the actual vapor pressure in the air in millibars
• saturatedVaporPressure= the saturated vapor pressure at a given temperature in millibars

Output:

• Relative Humidity= the relative humidity in percentage

Data validation

Both the actual vapor pressure and the saturated vapor pressure should be positive numbers.

Summary

This formula provides a straightforward calculation for determining the relative humidity, a critical measurement in meteorology and environmental monitoring.
