Simulation, Measurement and Spectral Analysis of Night Sky light Background

Abstract

Spectral measurement of the night sky provides important information about natural light sources and light pollution. Analysis of spectral data enables identification of interesting events occurring in the atmosphere. We describe used method and technical solution, as well as the first obtained results. Photometric and spectral simulations of the night sky light which were performed under laboratory conditions. Our test results are compared with the measured data of the whole night sky depending on location and timing. The outdoor measurement provided spectroscopic data for examining the light pollution and night sky light background. In the long run, spectroscopic data from the whole sky are recorded and statistically evaluated, which provides base for the noise signal eduction. The obtained noise signal is used as a reference in further research focused on rare events in the atmosphere.
