Keywords:sky-glow, rate of sky-glow variation by time, light pollution, quantification

We can watch stars clearly in the mountains, but we can't watch them clearly in the urban areas. So we were interested in light pollution, and we have been researching for sky-glow since 2002.
Light pollution is that artificial lights exert bad effects upon environment. From the research by our seniors, we realized sky-glow is had major effects by the weather conditions and the environmental index.
J.Bortle and S.Albers researched for quantifying the dark night sky in 2001, but the "LPI-S" we defined is quantification of the night sky brightened by artificial lights.
We want to enlighten light pollution using LPI-S not only in Japan but also all over the world, we hope to reduce wasteful energy.
