SEA ICE THICKNESS MEASUREMENT BY GROUND PENETRATING RADAR FOR GROUND TRUTH OF MICROWAVE REMOTE SENSING DATA
Sea ice thickness measurement, Microwave remote sensing Ground truth Ground Penetrating Radar Brackish lake Finite-Difference Time-Domain method Dielectric constant
2018/5/15
Observation of sea ice thickness is one of key issues to understand regional effect of global warming. One of approaches to monitor sea ice in large area is microwave remote sensing data analysis. How...
THIN ICE AREA EXTRACTION IN THE SEASONAL SEA ICE ZONES OF THE NORTHERN HEMISPHERE USING MODIS DATA
Sea Ice Optical Sensor Global Warming Glaciology
2018/5/14
Sea ice has an important role of reflecting the solar radiation back into space. However, once the sea ice area melts, the area starts to absorb the solar radiation which accelerates the global warmin...
SEA ICE DRIFT MONITORING IN THE BOHAI SEA BASED ON GF4 SATELLITE
GF4 image Sea ice Sift MCC Monitor
2018/5/17
The Bohai Sea is the inland sea with the highest latitude in China. In winter, the phenomenon of freezing occurs in the Bohai Sea due to frequent cold wave influx. According to historical records, the...

Remote sensing science is one of the most modern approaches for studying oceans, littoral regions, seas and large lakes, as well as sea ice covered regions. An important aspect of remote sensing scien...
FORECASTING ANTARCTIC SEA ICE CONCENTRATIONS USING RESULTS OF TEMPORAL MIXTURE ANALYSIS
Temporal mixture analysis times series model sea ice concentration AR model
2016/11/30
Sea ice concentration (SIC) data acquired by passive microwave sensors at daily temporal frequencies over extended areas provide seasonal characteristics of sea ice dynamics and play a key role as an ...
GLOBAL CHANGES IN THE SEA ICE COVER AND ASSOCIATED SURFACE TEMPERATURE CHANGES
Global sea ice surface temperature trends climate change remote sensing
2016/11/30
The trends in the sea ice cover in the two hemispheres have been observed to be asymmetric with the rate of change in the Arctic being negative at −3.8 % per decade while that of the Antar...

RADARSAT SAR Georeferencing Real-time Pollution Snow Ice Detection
2015/12/17
Synthetic aperture radar (SAR) data from RADARSAT-1 are an important operational data source for several ice centres around the world. Sea ice monitoring has been the most successful real-time operati...
HIGH RESOLUTION MOTION ESTIMATION OF SEA ICE USING AN IMPLICIT QUAD-TREE APPROACH
RADARSAT motion estimation Quadtree decomposition phase correlation line integral convolution
2015/9/17
In this paper we estimate the motion between time-lagged Synthetic Aperture Radar (SAR) image pairs via an implicit quad-tree scheme. The algorithm provides a means to estimate motion at a spatial res...
The use of remote sensing is necessary for monitor wide sea ice areas. However, since different scale sea ices often show similar
geometrical shapes and patterns like fractal, it is not easy for uns...
