arXiv preprint astro-ph/9811234, 1998•arxiv.orgWe obtained the map of the zenith brightness of the night sky in Italy. The artificial sky
brightness in each site is computed by integration of the contributions by each unitary area
of surface obtained by applying a propagation function to the upward emission of the area
as obtained from DMSP satellite night-time images. We also evaluated the emission versus
population relationship comparing the relative emissions of a number of cities of various
populations.
