Distributed Temperature Sensing (DTS) is an emerging technology designed to measure temperatures by means of optical fibers functioning as linear sensors. Temperatures are recorded along the optical sensor cable as a continuous profile. Typically the DTS systems can record temperature to a spatial resolution of 1 meter with accuracy to within ±1°C at a resolution of 0.01°C at distances up to greater than 30 km.

We are fortunate to be partnered with the Center for Transformative Environmental Monitoring Systems (CTEMPS) for this study, who will be providing their equipment and expertise during our 2022 and 2023 study design and data collection efforts.
