CP-IRGS: A Region-Based Segmentation of Multilook Complex Compact Polarimetric SAR Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The Canadian RADARSAT constellation mission (RCM) is represented by three synthetic aperture radar (SAR) satellites, each of which includes a compact polarimetry (CP) mode. CP is advantageous because it provides increased backscatter information relative

Large-scale sea ice motion from Sentinel-1 and the RADARSAT Constellation Mission [PDF]

, 2021
Abstract. As Arctic sea ice extent continues to decline, remote sensing observations are becoming even more vital for the monitoring and understanding of sea ice. Recently, the sea ice community has entered a new era of synthetic aperture radar (SAR) satellites operating at C-band with the launch of Sentinel-1A in 2014, Sentinel-1B in 2016 and the ...

Interlinked Dynamics of Rice Cultivation Intensity and Ground Subsidence: Spatio‐Temporal Insights Into Water Resource Implications From Multi‐Year Spaceborne SAR Analysis

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Sustainable rice cultivation is vital to meet global food demands, particularly in regions relying on groundwater for irrigation. Over‐pumping, however, can cause significant ground subsidence, threatening both infrastructure and agricultural sustainability.

Retrieval and Attribution of Tropical Cyclone Vertical Tilt From SAR and Infrared Satellite Imagery

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Tropical cyclones (TCs) are destructive natural hazards, and their vertical tilt, defined as the displacement between the sea surface center and cloud top center, plays a key role in storm structure and intensity changes. This study constructed a global satellite‐based tilt data set from 1,024 paired synthetic aperture radar (SAR) and infrared

Investigation of C-Band SAR Polarimetry for Mapping a High-Tidal Coastal Environment in Northern Canada

Remote Sensing, 2020
Synthetic Aperture Radar (SAR) has been used in characterizing intertidal zones along northern Canadian coastlines. RADARSAT-2, with its full polarimetric information, has been considered for monitoring these vulnerable ecosystems and helping enhance the

Synoptic Controls of Extreme Ice Area Flux Events Along Nares Strait

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Nares Strait, the channel between Ellesmere Island and northwest Greenland, connects the Arctic Ocean's Lincoln Sea to northern Baffin Bay. The transport of thick, multi‐year sea ice southward down the Strait contributes to the overall loss of this important ice class from the Arctic.

Oil Spill Candidate Detection Using a Conditional Random Field Model on Simulated Compact Polarimetric Imagery

Canadian Journal of Remote Sensing, 2022
Although the compact polarimetric (CP) synthetic aperture radar (SAR) mode of the RADARSAT Constellation Mission (RCM) offers new opportunities for oil spill candidate detection, there has not been an efficient machine learning model explicitly designed ...

Identifying Thermodynamic Regimes of CO2 Gas Exchange During the Melt Transition on First‐Year Sea Ice Using a Multi‐Sensor Synthetic Aperture Radar Approach

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Few multi‐year observations of CO2 gas exchange exist over melting first year sea ice (FYI). We report 4 years of CO2 flux data during the melt season in Dease Strait, Nunavut, Canada. Utilizing a dried, closed‐path eddy covariance system on an island within the strait, we identify two statistically distinct CO2 flux melt regimes: a pre‐pond ...
