Skyglow is a form of light pollution caused by artificial light scattered back within the atmosphere. We found that skyglow is dramatically amplified by clouds and snow on the ground (higher albedo), which we term "snowglow". Measurements in a suburban area, where the Milky Way is visible during moonless clear nights, revealed a zenith luminance 1000 times brighter than a clear sky reference and 3500 times brighter than a cloudy sky reference. A horizontal illuminance of 0.79 lx, two times higher than the maximum possible full moon, was measured. This represents a very high level of ecological light pollution as information on lunar cycles will be masked in these conditions. Strategies on how to reduce "snowglow" are discussed. View this paper
