***LakeIce*** consists of pixel-level backscatter (reflection) values from satellite images of an area of approximately 6,000 km<sup>2</sup> in Yukon, Canada [1, 2]. The time series are extracted over three decades from ERS-1/2, Radarsat, and Sentinel-1 synthetic aperture radar satellites, which all use the C-band range of microwave frequencies (4-8GHz). This is a pixel-level dataset, such that each time series represents values over time for single pixel. The satellites used in this case have different spatial resolutions, resulting in a mixture of effective pixel sizes of between 12.5m, 30m, and 50m. The processed dataset contains 129,280 (univariate) time series each of length 161, representing daily data over near 6 months (October to March), with three classes, labelled manually, representing bedfast ice, floating ice, and land. (The original data has been calibrated and speckle-filtered, and then interpolated to provide daily values for the relevant period [1].) This version of the dataset has been split into stratified random cross-validation folds.
