The Tahoe Environmental Observatory Network: A New Era in Climate Monitoring
In a significant stride towards understanding environmental shifts in the Lake Tahoe region, the Tahoe Environmental Observatory Network (TEON) has been officially launched. This initiative is a collaborative effort by the University of Nevada, Reno (UNR), the U.S. Forest Service, and the Tahoe Science Advisory Council, with support from NV Energy.
After two years of meticulous planning and development, TEON now integrates data from a comprehensive network of sensors monitoring weather, water quality, and other vital environmental metrics. According to Sudeep Chandra, director of UNR’s Tahoe Institute for Global Sustainability, the network’s primary aim is to illuminate the impacts of climate changes on the surrounding land and water bodies.
“The original idea behind creating the Tahoe Environmental Observatory Network is to try to understand the big changes that are happening at Lake Tahoe when it comes to climate, climate to land and land to water,” Chandra explained.
Currently, the network encompasses approximately 120 sensors strategically distributed across the Lake Tahoe basin, covering the west, east, and north shores, with additional coverage in the south. These sensors are designed to measure various environmental conditions, including water quality, temperature, and weather, with data updates occurring as frequently as every 10 minutes to hourly.
Data collected by these sensors is processed and stored at UNR, allowing for real-time monitoring via the TEON website. This system provides invaluable insights into the effects of significant weather phenomena, such as rain-on-snow events or El Niño storms, on stream and lake water quality. Chandra highlighted the network’s capacity to document these impacts, stating, “They allow us to see in real time how a big rain-on-snow event or rain coming in, for example, from these new El Niño storms, might change stream water quality and then affect the lake’s water quality.”
The centralized online platform serves as a comprehensive resource for researchers, land managers, and the public, enabling them to observe environmental changes as they occur. Looking ahead, Chandra envisions the network evolving into an early warning system, capable of detecting potential environmental threats such as algae or bacteria growth in Lake Tahoe.
