Light pollution can be rigorously described in terms of the volume concentration of anthropogenic photons (quanta of light) in the Earth’s atmosphere.
This formulation, consistent with the basic physics of light emission, scattering and absorption, allows light pollution levels to be expressed in terms of particle volume concentrations, quite analogous to what is currently done with other classic pollutants, such as fine particles. or molecular contaminants.
In this work, we provide the explicit conversion equations between photon volume concentration and traditional light photometric quantities. This equivalent description of light pollution levels provides relevant information that helps identify artificial light at night as a standard pollutant. It also allows a complementary way of expressing artificial light exposures for environmental and public health research and regulatory purposes.
