Advances in InSAR Analysis of Permafrost Terrain

Permafrost and Periglacial Processes, Volume 35, Issue 4, Page 544-556, October/December 2024.
ABSTRACT Differential interferometric synthetic aperture radar (InSAR) is a remote sensing technique for measuring surface displacements with precision down to millimeters, most commonly from satellites. In permafrost landscapes, InSAR measurements can provide valuable information on geomorphic processes and hazards, including thaw subsidence and frost

Multi‐Platform Observations of Severe Typhoon Koinu

Earth and Space Science, Volume 11, Issue 3, March 2024.
Abstract Severe Typhoon Koinu passed south of Hong Kong on 8 and 9 October 2023, triggering the issuance of the Increasing Gale or Storm Signal No. 9, the second highest tropical cyclone (TC) warning signal in Hong Kong. Koinu was a difficult case for TC warning service due to its compact size and rather erratic movement over the coastal waters of ...
