Observing the Solar Eclipse Over Lake Erie

On April 8th, observers across Northeast Ohio witnessed a once-in-a-lifetime total solar eclipse, an event where the moon obscures the sun, casting a shadow over Earth. This rare phenomenon offers a unique opportunity for data collection, particularly regarding its impact on local environmental conditions.

Using the Smart Lake Erie Watershed to Gather Data Insights During the Eclipse

Cleveland Water Alliance spearheads the Smart Lake Erie Watershed (SLEW), which employs advanced sensor technology to monitor environmental parameters throughout the watershed. This initiative enables precise data collection and analysis, enhancing our understanding and management of Lake Erie's resources. We utilized our sensors throughout the SLEW to gather data during this phenomenon. 

During the eclipse, our network of sensors captured valuable data: Our Chagrin Harbor station experienced a temperature drop of 12.6°F in 30 minutes, Avon saw a decrease of 5.76°F, and Euclid Park recorded a 7.2°F drop over 70 minutes. Additionally, a noticeable dip in solar radiation was observed between 2 PM and 4:30 PM across these locations, coinciding with totality. These findings highlight the significant, albeit temporary, environmental changes triggered by the eclipse.
