Brief communication: Comparison of the performance of thermistors and digital temperature sensors in a mountain permafrost borehole

Monitoring mountain-permafrost temperatures in boreholes is challenging regarding the resilience and long-term temperature stability of the sensor systems. Whilst resistance thermistors boast a high accuracy, they are prone to drift when exposed to moisture, pressure or cable strain. Supplementing o...
