Measurements on air temperature, the total radiation leading to ablation and snow levels by the weather monitoring station at the Tungnaá Glacier in the summer of 2013
The temperature was below freezing in May and there was no ablation. The temperature increased in May/June and radiation providing melt energy increased. Winter snow and glacial ice also began to melt and these levels remained stable until the middle of August. The average temperature and total radiation decreased after this. The summer of 2013 was rather cold and ablation levels were low.
