SH2RH

specific humidity \(q\) (\(kg/kg\))

temperature in Kelvin (K) or in degree Celsius (&lt;U+00B0&gt;C)

atmospheric pressure in Pascal (Pa). The default is standard atmospheric pressure of 101325Pa.

logical indicator whether temperature is in Kelvin (K). The default value is TRUE.

Climate models usually provide specific humidity only; however, relative humidity is used to compute <a href="https://www.weather.gov/ama/heatindex">heat index</a> that is really useful for health impacts studies. This function converts specific humidity \(q\) into relative humidity \(\psi\) at temperature \(t\) and under atmospheric pressure \(q\).

Vapor pressure, relative humidity, absolute humidity, specific humidity, and mixing ratio are commonly used water vapor measures in meteorology. This R package provides functions for calculating saturation vapor pressure (hPa), partial water vapor pressure (Pa), relative humidity (%), absolute humidity (kg/m^3), specific humidity (kg/kg), and mixing ratio (kg/kg) from temperature (K) and dew point (K). Conversion functions between humidity measures are also provided.
