Fast-response thermistors are tiny sensors that measure the temperature of the snow. In the SOS Project, the thermistors are set up at small spatial intervals to measure temperature variations within the snowpack.

Number deployed on SOS Project: 24

Make/model used on SOS Project: Campbell Scientific

Daniel Hogan, a graduate student at University of Washington and SOS Project researcher, describes the function of a thermistor profile at the Kettle Ponds study site in Gothic, Colorado.
