The dataset consists of image files (`JPG`) of Lake Tarfala, with the date and time (Swedish daylight saving time, UTC+2) included in each photo.
The pictures were acquired using a camera positioned on the mountain flank along Lake Tarfala’s north-eastern shore, at ~67.9° N, 18.6° E, at 1220 m above sea level.
The data were collected using a Hunter Orion Trail Camera 4G. The camera elevation is 1.8 m above ground. Each JPG file has a size of ~2.4 MB. The total size of the dataset is ~1.27 GB.
During periods, fog, snow and/or rain obscures the view of the lake. Also, due to shorter periods of daylight during autumn, the number of dark images between dusk and dawn successively increased. These are however not excluded from the dataset.
