我们展示了第一张关于海平面天顶人造夜空亮度的世界地图集。基于辐射校准的高分辨率 DMSP 卫星数据和大气中光传播的精确建模，它提供了人类如何将自己笼罩在发光雾中的近乎全球的图景。通过将 Atlas 与美国能源部 (DOE) 人口密度数据库进行比较，我们确定了生活在给定亮度天空下的人口比例。世界上大约三分之二的人口以及美国（不包括阿拉斯加和夏威夷）和欧盟 99% 的人口居住在夜空超过污染状态阈值的地区。假设平均眼睛功能正常，大约五分之一的世界人口、超过三分之二的美国人口和超过一半的欧盟人口已经丧失了肉眼对银河系的可见度。最后，由于天空亮度的原因，大约十分之一的世界人口、超过 40% 的美国人口和六分之一的欧盟人口不再用适应夜视的眼睛观看天空。
We present the first World Atlas of the zenith artificial night sky brightness at sea level. Based on radiance-calibrated high-resolution DMSP satellite data and on accurate modelling of light propagation in the atmosphere., it provides a nearly global picture of how mankind is proceeding to envelop itself in a luminous fog. Comparing the Atlas with the United States Department of Energy (DOE) population density data base, we determined the fraction of population who are living under a sky of given brightness. About two-thirds of the World population and 99 per cent of the population in the United States (excluding Alaska and Hawaii) and European Union live in areas where the night sky is above the threshold set for polluted status. Assuming average eye functionality, about one-fifth of the World population, more than two-thirds of the United States population and more than one half of the European Union population have already lost naked eye visibility of the Milky Way. Finally, about one-tenth of the World population, more than 40 per cent of the United States population and one sixth of the European Union population no longer view the heavens with the eye adapted to night vision, because of the sky brightness.
