An Automatic Method to Detect Lake Ice Phenology Using MODIS Daily Temperature Imagery

open access: yesRemote Sensing, 2021
Lake ice phenology is a climate-sensitive indicator. However, ground-based monitoring suffers from the limitations of human vision and the difficulty of its implementation in harsh environments.

Lake Ice Phenology Extraction using Machine Learning Methodology

open access: yesIOP Conference Series: Earth and Environmental Science, 2020
Abstract Lake-ice phenology is one of the key cryosphere indicators. Based on changes in time series of daily lake ice coverage and the microwave brightness temperature, two machine-learning methods were selected for estimating the phenology of lake ice.

A lake ice phenology dataset for the Northern Hemisphere based on passive microwave remote sensing

open access: yesBig Earth Data, 2022

Sea ice phenology in the Caspian Sea

open access: yesAdvances in Oceanography and Limnology, 2021
To understand the spatial and temporal variations in the extent and timing of sea ice in the Caspian Sea (CS), 15 years of sea ice presence and its phenology (freeze-up, break-up, and duration) were studied in the Northern CS (NCS) for a period from 2004 to 2018.

Climate change at the ecosystem scale: a 50-year record in New Hampshire [PDF]

open access: yes, 2012
Observing the full range of climate change impacts at the local scale is difficult. Predicted rates of change are often small relative to interannual variability, and few locations have sufficiently comprehensive long-term records of environmental ...

Observational evidence for the convective transport of dust over the central United States [PDF]

open access: yes, 2016
Bulk aerosol composition and aerosol size distributions measured aboard the DC-8 aircraft during the Deep Convective Clouds and Chemistry Experiment mission in May/June 2012 were used to investigate the transport of mineral dust through nine storms ...

Historical changes in the phenology of British Odonata are related to climate [PDF]

open access: yes, 2007
Responses of biota to climate change take a number of forms including distributional shifts, behavioural changes and life history changes. This study examined an extensive set of biological records to investigate changes in the timing of life history ...

Analysis of ice phenology of lakes on the Tibetan Plateau from MODIS data [PDF]

open access: yesThe Cryosphere, 2013
The Tibetan Plateau includes a large system of endorheic (closed basin) lakes. Lake ice phenology, i.e. the timing of freeze-up and break-up and the duration of the ice cover may provide valuable information about climate variations in this region.

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 ...
