The Role of Climate and Lake Size in Regulating the Ice Phenology of Boreal Lakes
Journal of Geophysical Research G: Biogeosciences, 2021AbstractWe quantified the relationships between seasonal air temperatures and ice phenology for a 0.54 km2 boreal lake in Northwestern Ontario, Canada using a 50‐year time series (1970–2019). Significant temporal trends in the duration of ice cover (−4.0 days decade−1) occurred over the study period and both ice‐on and ice‐off dates were highly ...

Approximating Lake Ice Phenology with Satellite Surface Temperature Data
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Studies of lake ice phenology have historically relied on limited in situ data. Satellite-derived temperature data provide an opportunity to better understand the climatological factors and trends behind ice phenology. Here we developed a model that uses daytime and nighttime surface temperature observations from the Moderate Resolution Imaging ...

Lake ice phenology changes in the northern hemisphere
2021<p>Lake-ice phenology is an essential indicator of climate change impact for different regions (Livingstone, 1997; Duguay, 2010), which helps understand the regional characters of synchrony and asynchrony. The observation of lake ice phenology includes ground observation and remote sensing inversion. Although some lakes have been observed

In Chapter 5 of this book, it is shown that the formation of ice on the surface of a lake (‘ice-on’) and its thawing and ultimate disappearance (‘ice-off’) are complex phenomena governed by mechanisms that involve many interacting meteorological (and some non-meteorological) forcing factors. Linking ice phenology – the timing of ice-on and ice-off – to

Climate change is leading to shifts in not only the average timing of phenological events, but also their variance and predictability. Increasing phenological variability creates a stochastic environment that is critically understudied, particularly in aquatic ecosystems.

Patterns and Trends in Southern Ontario Lake ice Phenology
Environmental Monitoring and Assessment, 2003An analysis is presented of 46 ice break up and 15 ice free season phenology data series obtained largely through volunteer monitoring efforts in Southern Ontario. Observations spanned the years 1853-2001. Available data included dates of ice formation and ice break up as well as the number of ice free days in a year.

Lake Ice phenology of small lakes: Impacts of climate variability in the Great Lakes region
Global and Planetary Change, 2011Abstract Formation of lake ice is common in lakes located in mid and high latitudes. Lake ice plays a vital role in heat storage, controlling lake water temperature, survival of aquatic ecosystems, and maintaining the bio diversity of lakes. Significant warming in air temperature during the cold season (October–May) may lead to reduced ice cover of ...

Investigating Lake Ice Phenology in Tibetan Plateau Using Satellite Data
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Lake ice phenology are considered as a sensitive indicator of global warming. In Tibetan Plateau (TP), differences exist in identifying lake ice phenology using remote sensing data because of the limited ground observation and difference in the sources of remote sensing and the available algorithms. In this study, four methods based on different remote

MODIS-observed variations of lake ice phenology in Xinjiang, China
Climatic Change, 2019Lakes sensitively respond to global and regional climate change, especially in arid areas. Using Moderate Resolution Imaging Spectroradiometer (MODIS) daily snow products, the lake ice phenology of 23 lakes in the Xinjiang Uygur Autonomous Region of China from 2001 to 2018 was extracted based on thresholds of ice/water pixel numbers, and their change ...
