During this period, the surface of Lake Tarfala transitions from being ice-free to ice-covered, an event referred to as \"ice-on\".\r\n\r\nThe dataset can be used to observe the ice-on event and to assign a date to it. Knowledge of lake ice phenology, i.e. seasonal formation and loss of the lacustrine ice cover, is of importance since the timing of ice-on impacts lake processes such as stratification and vertical mixing. \r\n\r\nThe pictures were acquired using a camera positioned on the mountain flank along Lake Tarfala\u2019s north-eastern shore, at 1220 m above sea level. In total, there are 542 images. The later the season, the more pictures are dark because of the approaching of the polar night.\r\n\r\n","url":"http:\/\/bolin.su.se\/data\/tarfala-kirchner-2023-ice-on-2022-1","keywords":["Lacustrine","Lake Ice ","Lacustrine","Observations","Lake Tarfala","Tarfala","Lake ice","Lake ice phenology","Ice-on","Earth science > Cryosphere > Snow\/ice > Lake ice"],"creator":{"@type":"Person","name":"Nina Kirchner, Annika Granebeck, Jamie Barnett, Maja Oscarsson"},"citation":"Kirchner, N., Weckstr\u00f6m, J., Jansen, J., Schenk, F., Barnett, J., Granebeck, A., Lepp\u00e4ranta, M., Korhola, A.
