Vapor Pressure — pres_vapor

Calculates vapor pressure from relative humidity and saturation vapor pressure.

Usage

pres_vapor_p(...)

# Default S3 method
pres_vapor_p(temp, rh, ...)

# S3 method for class 'weather_station'
pres_vapor_p(weather_station, ...)

Arguments

...: Named station fields, site parameters or model assumptions.
temp: Air temperature in degrees C.
rh: Relative humidity in percent.
weather_station: A weather_station object.

Value

Vapor pressure in hPa.

Details

The vapor pressure ($e$) is calculated as: $$e = \frac{RH}{100} \cdot e_s$$ where: $RH$ is the relative humidity in %, $e_s$ is the saturation vapor pressure in hPa.
