a few centimeters from the stick (Appendix C, Fig. C5). Visual inspections during late spring (May 2016) revealed thatmelting occurred around the bamboo stick, leaving an air gaparound the stick. The temperature sensors were neverthelesswell away from the stick (in a horizontal direction) and remained embedded in the snow. The height of the sensors waschanged on a number of occasions following damage by reindeer. Sensors were originally mounted at heights of 0.35 and0.48 m to record snow temperatures, but these heights werechanged during subsequent years (Table 2). Information concerning the changes in sensor height is included in the datadescription that accompanies the data (Appendix C, Fig. C5).
