Detailed station information

Snow on the roof of the detector housing cannot be removed due to the danger of avalanches and falling rocks. Therefore it is possible that a rather large amount of snow can accumulate on the roof of the housing mainly during winter and spring time. Special incidents such as strong wind or melting snow are noted in a journal.
