Abstract

The objective of this investigation was to study the evolution of light pollution in Madrid from 2010 to 2020 using measurements of the night sky's brightness with its associated color indices via nonparametric statistical techniques. The monitoring station at Universidad Complutense de Madrid (UCM) used: a pairs of Sky Quality Meters (SQMs), a Telescope Encoder Sky Sensor-WiFi (TESS-W) broadband photometry, and an All-Sky Transmission Monitor camera (AstMon) for measuring brightness in Johnson B, V, and R photometric band. Collected data showed that night sky brightness has varied due to both manufacturing technology and lamp power. The collected data was measured before, during, and after a major streetlight retro tin 2015. Changes included replacing High-Pressure Sodium (HPS) lamp bulbs with lower power Light-Emitting Diode (LED) + HPS bulbs (from 250 W /150 W to 150 W /70 W).
