Simulation, Measurement and Spectral Analysis of Night Sky Light Background

Abstract

Spectral measurements of the night sky provide important information about natural light sources and light pollution. Analysis of spectral data enables identification of interesting events occurring in the atmosphere. We describe the used method and the technical solution, as well as first obtained results. Photometric and spectral simulations of the night sky light were performed under laboratory conditions. The results were compared with measured data of the whole night sky with respect to location and timing. The outdoor measurements provided spectroscopic data for examining the light pollution and night sky light background.
