我们将Roy Garstang介绍和开发的天空亮度建模技术应用于美国空军防御气象卫星计划业务线扫描系统和GTOPO 30进行的向上人造光通量的高分辨率卫星测量（美国地质调查局EROS数据中心的全球数字高程模型）数字高程数据，以预测在一系列大气气溶胶含量的主要天文光度带中给定地点的夜空亮度分布。这一方法以全球数据为基础，并考虑到海拔、地球曲率和山脉屏蔽，因此可以评价世界上任何地点整个天空的天空辉光状况，以评价其演变情况，理清周围地区各个来源的贡献，并查明主要的贡献来源。天空亮度、肉眼恒星可见度和望远镜极限星等被生成为三维阵列，其轴是天空中的位置和大气透明度。我们将我们的结果与现有的测量结果进行比较。
We apply the sky brightness modelling technique introduced and developed by Roy Garstang to high-resolution satellite measurements of upward artificial light flux carried out with the US Air Force Defense Meteorological Satellite Program Operational Linescan System and to GTOPO30 (a global digital elevation model by the US Geological Survey's EROS Data Centre) digital elevation data in order to predict the brightness distribution of the night sky at a given site in the primary astronomical photometric bands for a range of atmospheric aerosol contents. This method, based on global data and accounting for elevation, Earth curvature and mountain screening, allows the evaluation of sky glow conditions over the entire sky for any site in the world, to evaluate its evolution, to disentangle the contribution of individual sources in the surrounding territory and to identify the main contributing sources. Sky brightness, naked eye stellar visibility and telescope limiting magnitude are produced as three-dimensional arrays, the axes of which are the position on the sky and the atmospheric clarity. We compare our results with available measurements.
