Reconstructing ice phenology of a lake with complex surface cover: a case study of Lake Ulansu during 1941–2023 [PDF]

open access: yesThe Cryosphere
Lake ice phenology plays a critical role in determining the hydrological and biogeochemical dynamics of catchments and regional climates. Lakes with complex shorelines and abundant aquatic vegetation are challenging for retrieving lake ice phenology via ...

Estimating ice phenology on large northern lakes from AMSR-E: algorithm development and application to Great Bear Lake and Great Slave Lake, Canada [PDF]

open access: yesThe Cryosphere, 2012
Time series of brightness temperatures (<i>T</i><sub>B</sub>) from the Advanced Microwave Scanning Radiometer–Earth Observing System (AMSR-E) are examined to determine ice phenology variables on the two largest lakes of northern ...

Fine-Resolution Mapping of Pan-Arctic Lake Ice-Off Phenology Based on Dense Sentinel-2 Time Series Data

open access: yesRemote Sensing, 2021
The timing of lake ice-off regulates biotic and abiotic processes in Arctic ecosystems. Due to the coarse spatial and temporal resolution of available satellite data, previous studies mainly focused on lake-scale investigations of melting/freezing ...

Simulating lake ice phenology using a coupled atmosphere–lake model at Nam Co, a typical deep alpine lake on the Tibetan Plateau [PDF]

open access: yesThe Cryosphere
Simulating the ice phenology of deep alpine lakes is important and challenging in coupled atmosphere–lake models. In this study, the Weather Research and Forecasting (WRF) model, coupled with two lake models, the freshwater lake (WRF–FLake) model and the

Continuous Loss of Global Lake Ice Across Two Centuries Revealed by Satellite Observations and Numerical Modeling

open access: yesGeophysical Research Letters, 2022
Lake ice loss has been detected worldwide due to recent climate warming, yet spatially and temporally detailed information on the changes in global ice phenology does not exist.

Ice Phenology in Eurasian Lakes over Spatial Location and Altitude

open access: yesWater, 2022
Eurasian freezing lakes cover an almost 180° wide longitude sector between the latitudes 30° and 75° N, and their altitudes range from below the sea surface level up to 5 km elevation. Ice phenology varies widely in this region. However, these variations and their influence factors have been little studied.

Southern Ocean Biogeochemical Argo detect under-ice phytoplankton growth before sea ice retreat [PDF]

open access: yesBiogeosciences, 2021
The seasonality of sea ice in the Southern Ocean has profound effects on the life cycle (phenology) of phytoplankton residing under the ice. The current literature investigating this relationship is primarily based on remote sensing, which often lacks ...

On thin ice: Linking elevation and long‐term losses of lake ice cover

open access: yesLimnology and Oceanography Letters, 2021
Despite long‐term analyses of lake ice phenology globally, comparatively little is known about high‐elevation lakes, for which climate shifts are thought to be occurring faster than at lower elevations. Using a 36‐yr dataset (1983–2018) on alpine lakes (>

Uncertainty and Variation of Remotely Sensed Lake Ice Phenology across the Tibetan Plateau

open access: yesRemote Sensing, 2018
In the Tibetan Plateau (TP), the changes of lake ice phenology not only reflect regional climate change, but also impose substantial ecohydrological impacts on the local environment.
