Bird spikes installed to deter seagulls had bent over the pyranometer, causing anomalous readings during these hours. The spikes were properly repositioned on September 29, 2025. We recommended using the component summation (DIR*cosSZA + DIF) to calculate SWD.-87.41146.721Lake Superior, Michigan, United States
