The high spatial resolution (2cm) vertical air-snow-ice-water temperature time series have been measured in an Arctic lake during winter seasons 2009-2020. Snow depth, ice thickness as well as the lake ice composition are retrieved from temperature time series. High quality meteorological parameters are available from Sodankylä weather station in the vicinity (12 km) from the lake.The data sets here are for a manuscript entitled as "Inter-annual variation of lake ice composition in the Arctic region: Results from observed high-resolution thermistor string"
