• Misdirected or misused light
• Inappropriate application of exterior lighting products
• Light causing a glow over urban/suburban areas

MethodologyMethodologyLight Pollution Measured by the DSS-7
Control: sky measured by DSS-7 in Montauk, NY
Variable: sky measured DSS-7 in Manhasset, NY
Procedure
Measured once a week in Montauk and imaged, measured once a week in Manhasset and imaged over 7 months
Measurement
Night light sources as observation points, visibility analysis
Analysis
Graph/map of data collected
Amounts vs. types of light pollution analyzed
