“…The halos of scattered light observed from space around ground light sources also provide interesting information. Sánchez de Miguel et al (2020) have shown that their scattered upward radiance is correlated with the downward one, and hence with the light perceived by ground-based observers as anthropogenic skyglow, thus providing a feasible tool for wide-area light pollution monitoring. Analysing these halos, Kocifaj and Bará (2020) developed a method for estimating the number-size distribution of aerosol particles in the nocturnal air column from the angular distribution of the upward scattered light.…”

Nighttime monitoring of the aerosol content of the lower atmosphere is a challenging task, because appropriate reference natural light sources are lacking. Here we show that the anthropogenic night sky brightness due to city lights can be successfully used for estimating the aerosol optical depth of arbitrarily thick atmospheric layers. This method requires measuring the zenith night sky brightness with two detectors located at the limiting layer altitudes. Combined with an estimate of the overall atmospheric optical depth (available from ground-based measurements or specific satellite products), the ratio of these radiances provides a direct estimate of the differential aerosol optical depth of the air column between these two altitudes. These measurements can be made with single-channel low-cost radiance detectors widely used by the light pollution research community.
