“…The thermodynamic length scales are here the light attenuation and heat conduction depths. The former is greater than ice thickness [27], while for daily cycles, the latter is 0.3 m (as reported in Leppäranta [2]). For snow cover, the corresponding length scales are 0.15 and 0.1 m. Figure 7.…”

To improve the understanding of the seasonal evolution of the mass and heat budget of ice-covered lakes in the cold and arid climate zone, in-situ observations were collected during two winters (2016–2017 and 2017–2018) in Lake Wuliangsuhai, Inner Mongolia, China. The mean snow thickness was 5.2 and 1.6 cm in these winters, due to low winter precipitation. The mean ice thickness was 50.9 and 36.1 cm, and the ice growth rate was 3.6 and 2.1 mm day−1 at the lower boundary of ice. Analyses of mass and heat balance data from two winters revealed that the surface heat budget was governed by solar radiation and terrestrial radiation. The net heat flux loss of the ice was 9–22 W m−2, affected by the snow and ice thickness. Compared to boreal lakes, Lake Wuliangsuhai received more solar radiation and heat flux from the water. The ice temperature had a strong diurnal variation, which was produced by the diurnal cycles of solar radiation, and air and water temperatures. These results expand our knowledge of the evolution of mass and heat balance in temperate lakes of mid-latitude arid areas.

“…In 35 days, the highest T a exceeded 0 • C and night-and-day freeze-thaw cycles occurred on the ice surface. This phenomenon was also observed in winter 2016 [27]. In winter 2018, the average diurnal variation in T a was 15.6 • C, and the maximum was 22.3 • C on February 13.…”

“…Snow and ice measurements similar to those in Lake Orajärvi have been recently initiated in Wulaingsuhai lake in an arid climate zone in Inner-Mongolia of China. The observations focused on lake ice mass balance (Lu et al, 2020) and energy budget, in particular the solar radiation (Cao et al, 2020). In a long run, the corresponding lake snow and ice measurements at both sites and possible similar observations in a thermokarst lake (e.g.…”

Abstract. Climate change and global warming strongly impact the cryosphere. The rise of air temperature and change of precipitation patterns lead to dramatic responses of snow and ice heat and mass balance. Sustainable field observations on lake air-snow-ice-water temperature regime have been carried out in Lake Orajärvi in the vicinity of the Finnish Space Centre, a Flagship Supersite in Sodankylä in Finnish Lapland since 2009. A thermistor string-based snow and ice mass balance buoy called “Snow and ice mass balance apparatus (SIMBA)” was deployed in the lake at the beginning of each ice season. In this paper, we describe snow and ice temperature regimes, snow depth, ice thickness, and ice compositions retrieved from SIMBA observations as well as meteorological variables based on high-quality observations at the Finnish Space Centre. Ice thickness in Lake Orajärvi showed an increasing trend. During the decade of data collection: 1) The November-May mean air temperature had an increasing trend of 0.16º C/year, and the interannual variations were highly correlated (r = 0.93) with the total seasonal accumulated precipitation; 2) The maximum granular ice thickness ranged from 15 to 80 % of the maximum total ice thickness; 3) The snow depth on lake ice was not correlated (r = 0.21) with the total precipitation. The data set can be applied to investigate the lake ice surface heat balance and the role of snow on lake ice mass balance, and to improve the parameterization of snow to ice transformation in snow/ice models.

“…The TriOS sensors provided the spectral reflectance, absorption, and transmittance of solar radiation over the 320–950 nm band (Cao et al., 2020). For the present DO analyses, the outgoing and penetrating measurements were not directly used because the snow layers were quite different between the TriOS and DO sites, 10 m apart from each other.…”

More than half of the world's lakes are seasonally ice-covered (Verpoorter et al., 2014). A large fraction of lakes are located between 60° and 66°N, where the annual ice season lasts more than 150 days (Leppäranta, 2015). An ice and snow covered lake is remarkably different than one with an open water surface with respect to the optical, thermal, and mechanical properties. Freezing of lakes brings a divergent seasonal aquatic environment compared with the open-water period in terms of lake physics, chemistry, and ecology. For instance, the lake ice cover largely reduces the solar radiation into the water body, keeps the water body cold, and shelters the water body from atmospheric deposition and wind stirring, weakening, or even ceasing the hydrodynamics (Kirillin et al., 2012). These physical changes can drive or facilitate the migration and transformation of nutrients and metals (
