USING SMOS PASSIVE MICROWAVE DATA TO DEVELOP SMAP FREEZE/THAW ALGORITHMS ADAPTED FOR THE CANADIAN SUBARCTIC
Passive Microwave Freeze-Thaw Frozen Soil SMOS Remote Sensing
2016/1/15
Seasonal terrestrial Freeze/Thaw cycle in Northern Quebec Tundra (Nunavik) was determined and evaluated with passive microwave observations. SMOS time series data were analyzed to examine seasonal var...
Freeze/thaw processes in complex permafrost landscapes of northern Siberia simulated using the TEM ecosystem model: impact of thermokarst ponds and lakes
Freeze/thaw processes complex permafrost landscapes northern Siberia simulated TEM ecosystem model thermokarst ponds and lakes
2014/12/19
Freeze/thaw (F/T) processes can be quite different under the various land surface types found in the complex tundra of the Arctic, such as polygonal tundra (wet center and dry rims), ponds, and thermo...
Feasibility of Characterizing Snowpack and the Freeze–Thaw State of Underlying Soil Using Multifrequency Active/Passive Microwave Data
Freeze Characterizing Snowpack Freeze–Thaw State
2013/9/2
Abstract—An ensemble-based data assimilation approach isdeveloped to characterize the snow water equivalent (SWE)and underlying soil freeze–thaw tate (including the soil surfacetemperature and both so...

Spatial and temporal variability of soil freeze-thaw cycling across Southern Alberta, Canada
Freeze-Thaw Soil Temperature Agro-Ecosystem Modeling Regional Climate Soil Science
2013/3/5
Soil freeze-thaw cycles play an important role in all aspects of agro-ecosystems, such as crop productivity, the evolution of the soil matrix, including trace-gas emissions. In regions that experience...
Changes in the near-surface soil freeze-thaw cycle on the Qinghai-Tibetan Plateau
Freeze–thaw cycle Permafrost Qinghai-Tibetan Plateau Mountain cryosphere Climate warming Microwave remote sensing Trend analysis
2013/9/2
Changes in the near-surface soil freeze–thaw cycle on the Qinghai-Tibetan Plateau (QTP) were detected using daily soil freeze/thaw states derived from Special Sensor Microwave/Im...
A new soil freeze/thaw discriminant algorithm using AMSR-E passive microwave imagery
soil freeze/thaw status microwave radiometer discrimination analysis AMSR-E
2013/9/2
The soil freeze–thaw controls the hydrological and carbon cycling and thus affects water and energy exchanges at land surface. This article reported a newly developed algorithm for distinguishing the ...
Effect of Multi-Treatment of Freeze-Thaw or Low Temperature on Wheat Starch Gel
furunori wheat starch gel freeze-thaw treatment
2008/4/20
We investigated the effect of multiple treatments (10, 20 and 30 times, one cycle of treatment: 24 h) of freeze-thaw (-30°C) or low temperature (4°C) on wheat starch gel for elucidation of the formati...
