Short summary
Long-term temperature measurements are challenging to carry out in mountain-permafrost boreholes. The widely used resistance thermistors are highly accurate but prone to drift when they are exposed to moisture, or the cable connecting them is stretched. We explore the possibility of supplementing them with digital sensors and analyse the performance of both systems at 15 depths in the same mountain-permafrost borehole.
