calcAD: Calculate Air Density

In ConSciR: Tools for Conservation Science

Calculate Air Density

Description

Function to calculate air density based on temperature (°C), relative humidity in (%), and atmospheric pressure (hPa).

Usage

calcAD(Temp, RH, P_atm = 1013.25, R_dry = 287.058, R_vap = 461.495, ...)

Arguments

Temp	Temperature (°Celsius)
RH	Relative Humidity (0-100%)
P_atm	Atmospheric pressure = 1013.25 (hPa)
R_dry	Specific gas constant for dry air = 287.058 (J/(kg·K))
R_vap	Specific gas constant for water vapor = 461.495 (J/(kg·K))
...	Addtional arguments to supply to calcPws

Value

Air density in kg/m³

filepath <- data_file_path("mydata.xlsx")
mydata <- readxl::read_excel(filepath, sheet = "mydata", n_max = 5)

mydata |> dplyr::mutate(AirDensity = calcAD(Temp, RH))
