Abstract Sea surface wind retrieval under extreme weather conditions is constrained by the sparse and irregular spatiotemporal sampling of Global Navigation Satellite System Reflectometry (GNSS‐R). This study presents a probabilistic wind field reconstruction framework for the Western North Pacific using Score‐Based Data Assimilation (SDA). A diffusion

Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Spaceborne bi- and multistatic SAR: potential and challenges [PDF]
Bi- and multistatic synthetic aperture radar (SAR) operates with distinct transmit and receive antennas that are mounted on separate platforms. Such a spatial separation has several operational advantages, which will increase the capability, reliability and flexibility of future SAR missions.

Interferometric Synthetic Aperture Radar (InSAR) for Monitoring Seasonal Snow
Abstract Interferometric Synthetic Aperture Radar (InSAR) offers a potential pathway for measuring seasonal snow water equivalent (SWE) and snow depth at spatial and temporal scales needed for basin‐scale hydrology. First proposed for seasonal snow more than 25 years ago, InSAR uses repeat‐pass radar phase differences to estimate changes in SWE or ...

Significant Decline in Carbon Storage at the Edges of Mangrove Forest
Abstract Quantitative analysis of blue carbon stored in mangrove ecosystems is essential for understanding their role in climate change mitigation. However, the impacts of edge effects in fragmented mangrove forests are often overlooked in large‐scale blue carbon assessments.

Azimuth Phase Coding by Up and Down Chirp Modulation for Range Ambiguity Suppression
High range ambiguity level will impair the spaceborne SAR image quality and hamper following SAR image applications. The range ambiguity suppression effect of the up and down chirp modulation on spaceborne SAR images is analyzed in this paper.
