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 ...

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 ...

Polarimetric Change Detection for Wetlands [PDF]
An exciting development in wetland mapping and monitoring is the use of SAR polarimetry which uses both magnitude and phase of the backscattered radar signal for information extraction.

Near‐Surface Ocean Current and Its Response to Wind Forcing
Abstract Ocean currents near the air‐sea interface are critical for understanding boundary layer processes and advancing coupled models. The near‐surface currents mediate air–sea fluxes and govern the transport of buoyant materials, yet the uppermost meter of the ocean remains sparsely observed and poorly represented in models.

Direct Assimilation of Satellite Visible and Near‐Infrared Radiances to Improve Aerosol Simulations
Abstract Existing satellite‐based aerosol data assimilation approaches mostly rely on assimilating retrieved aerosol products, which suffer from inconsistencies between retrieval assumptions and model representations, as well as uncertainties in the retrieved aerosol parameters.
