Climate change and global warming have a strong impact on the cryosphere. Global warming and precipitation changes will result in a strong response to the heat and mass balance of ice and snow, but current research on high latitude lake ice changes lacks effective observations. Since 2009, the Finnish Meteorological Institute has carried out on-site SIMBA buoy observations of the air-snow-ice-water temperature field of Lake Orajärvi in northern Finland for more than 10 years, combined with high-quality meteorological observations from the Finnish Space Center. The observational data constitute a set of lake ice multi-source data sets, which can be used for multi-scale ice and snow and lake ice thermodynamic mechanism research. The dataset was completed by Prof. Fei Zheng from ICCES and Dr. Bin Cheng from the Finnish Meteorological Institute.
