Classes

class ParticleConcentration (radius_range=(0, inf), specific=False, stp=False, name=None, unit='m^-3')

Helper class that provides a standard way to create an ABC using inheritance.

stp toggles expressing the concentration in terms of standard temperature and pressure conditions (ground level of the ICAO standard atmosphere, zero humidity)
