airRho {oce} | R Documentation |
Compute, rho, the in-situ density of air.
airRho(temperature, pressure, humidity)
temperature |
in-situ temperature [degC] |
pressure |
pressure in Pa (NOT kPa) – ignored at present |
humidity |
ignored at present |
This will eventually be a proper equation of state, but for now it's just returns something from wikipedia (i.e. not trustworthy), and not using humidity.
In-situ air density [kg/m^3].
