Automated ice station Lotus was deployed in the lake for measurements during the ice seasons (Table 1). The data include atmospheric surface layer (temperature, humidity, wind speed and direction, solar radiation), snow and ice cover (radiative surface temperature, snow depth, vertical temperature distribution, attenuation of sunlight), and lake water body beneath the ice (temperature, electric conductivity, sunlight, current velocity).
