Summary: We propose a Simple Lake Ice Model to calculate the growth rate of lake ice in a cold and relatively dry climate. With a focus on Lake St. Moritz, Switzerland, we provide a tool that can calculate the growth rate of the ice layer based on air temperature, snow cover, and other input data. We also demonstrate the positive effect of grooming the snow on the ice thickening rate and evaluate the sensitivity of simulated ice thickness to increasing mean temperature.

Summary: A remote sensing-derived lake ice phenology database covering all lakes in Alaska from 2000 to 2019 was constructed to analyze the trends of earlier breakup and later freezeup of lake ice in the region. The dataset showed significant trends towards earlier or later ice breakup and freezeup for various lakes, with most significant trends observed in lakes north of the Brooks Range. This dataset contributes to the understanding of interactions between lake processes and climate change, supporting research on biogeochemical, limnological, and ecological regimes in Alaska and pan-Arctic regions.

Summary: Accurate monitoring of snow and ice dynamics in the Arctic is crucial for understanding climate change impacts and predicting feedback on global climate. Traditional remote sensing methods have limitations in long-term observations of polar regions. This study systematically assessed the use of moonlight remote sensing to monitor snow/ice dynamics during dark Arctic winters. Using VIIRS/DNB time series data and object-oriented Random Forests algorithm, we achieved high accuracy in revealing the spatiotemporal dynamics of snow/ice covers from 2012 to 2022. Our findings demonstrate the potential of moonlight remote sensing for continuous monitoring in the Arctic and contribute to polar studies and climate change research.

Summary: Satellite observations from 2014 to 2020 reveal repeated and rapid drainages of supraglacial lakes at the grounding zone of the Amery Ice Shelf in East Antarctica. These drainages coincide with periods of high daily tidal amplitude, indicating the presence of tidal forces in the ice shelf grounding zone. The findings suggest that grounding zone drainage events may inhibit ice shelf meltwater accumulation, providing a potential stabilizing mechanism despite increased melting in these regions.

Summary: Water surface albedo can affect the heat flux and energy balance at the water-atmosphere interface, thereby impacting key climate-change factors. Existing global water cycle models often use specific values for water surface albedo, leading to estimation errors of 5-15% due to time and location differences. This research developed a lake albedo inversion model based on the Sentinel-2 MSI sensor, using a method to convert narrowband albedo to broadband albedo.

Summary: The study compared two years of monitoring data in Ward Hunt Lake in the Canadian High Arctic and found that the loss of multi-year ice cover can significantly impact the limnological properties of polar lakes, leading to water column mixing and temperature changes. Extreme warming events are likely to shift polar lakes from a regime of continuous thick ice cover to irregular ice loss and unstable limnological conditions that vary greatly from year to year.

Summary: Extreme snowfall events have been increasing in the Tibetan Plateau and have caused greater variations in snow cover conditions. This study analyzed the impacts of snow cover on water-heat transfer in alpine meadows using five years of observation data. The findings indicate that snow cover decreases soil temperature and inhibits extremely low temperatures in the soil. Different snow conditions also affect soil thawing, snowmelt infiltration, and surface soil water evaporation. The study provides insights into soil water-heat transfer under extreme snow cover conditions in the Tibetan Plateau.

Summary: This paper investigates the local and non-local climatic effects of wetter arid areas of Northwestern China (ANWC) in summer using a fully coupled climate model. The results show that with increasing soil moisture, the local air temperature decreases significantly and precipitation increases during summer. The wetter ANWC leads to a warmer and rainless climate over the Central part of North China Plain (CNCP), while its influence on Tibetan Plateau (TP) precipitation is negligible due to the high altitude.

Summary: The Arctic is warming at an above-average rate, and small, shallow waterbodies such as ponds are vulnerable to this warming due to their low thermal inertia compared to larger lakes. While the response of pond methane emissions to warming is uncertain, a new model called MeEP has been developed to investigate the methane emission response of polygonal-tundra ponds in northeastern Siberia. The model differentiates between pond types and pathways of methane emissions and shows an approximately linear increase in emissions with temperature increase.

Summary: This study evaluates the soil moisture and temperature analysis of the global atmospheric model in Western Europe using in situ observations. It finds that the seasonal temperature trends are reproduced better than the soil moisture trends. Numerical experiments show that implementing the Mualem-van Genuchten water retention curve improves the description of soil moisture transfer compared to the Brooks-Corey parameterization. Inaccurate soil granulometric composition profiling contributes to soil moisture errors, highlighting the need for state-of-the-art soil characteristic databases.

Summary: Empirical evidence shows that lakes and reservoirs are warming globally. Previous studies on the impacts of climate change on lakes have been limited and fragmented, resulting in a lack of understanding of the main effects at global and regional scales. The simulation protocol developed by the ISIMIP Lake Sector aims to address this gap by using multiple lake models and climate change scenarios to project future impacts on lake water quality and biogeochemistry.
