bigleaf (version 0.7.0)

air.density: Air Density

Description

Air density of moist air from air temperature and pressure.

Usage

air.density(Tair, pressure, constants = bigleaf.constants())

Arguments

Tair

Air temperature (deg C)

pressure

Atmospheric pressure (kPa)

constants

Kelvin - conversion degC to Kelvin Rd - gas constant of dry air (J kg-1 K-1) kPa2Pa - conversion kilopascal (kPa) to pascal (Pa)

Value

\(\rho\)

air density (kg m-3)

Details

Air density (\(\rho\)) is calculated as:

$$\rho = pressure / (Rd * Tair)$$
