In August 2012 this was changed to a CR1000 data logger.\r As the station is situated on a southfacing slope (dominating leeward side during winter in Zackenberg), the station has been covered in snow during several winters, resulting in low power and missing data.\r Soil temperature is also measured at the station, but data not published in the database, due to problems with propagating datalogger temperature.
