During a rather harsh winter in Iceland. Two SIL stations have failed on top of Mýrdalsjökull glacier. This are the SIL stations Austmannsbunga and Etnu glacier (local name). The reason for the failure is ice that loaded on to the mast the SIL stations. Making it fall down on the ground. Therefor making the SIL stations lost contact with Icelandic Meteorological Office and University of Iceland. University of Iceland and Icelandic Meteorological Office plan a trip soon to this area of Mýrdalsjökull glacier too fix this SIL stations that are broken. But the weather has too improve first in Iceland before that can happen.
I also suspect this is the problem with the SIL stations on Vatnajökull glacier. That SIL station just has the term “vot“.
