In skgrange/threadr: Tools to Thread Pieces Of Data Analysis Together

Function to calculate the mixing ratio of water.

Description

calculate_water_volume_mixing_ratio uses the August-Roche-Magnus equation to calculate the partial pressure of air and this is divided by air pressure to calculate the mixing ratio of water in dry air.

Usage

calculate_water_volume_mixing_ratio(temp, rh, pressure, as_percent = FALSE)

Arguments

temp	Temperature in degrees Celsius – usually air temperature.
rh	Relative humidity in percent.
pressure	Pressure (usually air pressure) in the units of hectopascal/millibar.
as_percent	Should the units used for the return be percentage rather than a ratio?

Value

Numeric vector with the units of a ratio or percentage if as_percent is TRUE.

Examples

# Calculate the mixing ratio of water from some observations in Zürich, at an
# elevation of ~ 430 m, therefore air pressure is relatively low
calculate_water_volume_mixing_ratio(13.3, 92.5, 976.5)

# Or as a percent
 calculate_water_volume_mixing_ratio(13.3, 92.5, 976.5, as_percent = TRUE)
