Assessment of AMSR2 Ice Extent and Ice Edge in the Arctic Using IMS

Remote Sensing, 2020
This work assesses the AMSR2 (the Advanced Microwave Scanning Radiometer 2) ice extent and ice edge in the Arctic using the ice extent products of NOAA’s Interactive Multisensor Snow and Ice Mapping System (IMS) from the period of July 2015 to July 2019.

Diffusion‐Based Reconstruction of Western North Pacific Surface Winds From CYGNSS for Tropical Cyclone Analysis

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 10, October 2026.
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

On the synergy of SMAP, AMSR2 AND SENTINEL-1 for retrieving soil moisture

International Journal of Applied Earth Observation and Geoinformation, 2018
An algorithm for retrieving soil moisture content (SMC) from synergic use of both active and passive microwave acquisitions is presented. The algorithm takes advantage of the integration of microwave data from SMAP, Sentinel-1 and AMSR2 for overcoming the SMAP radar failure and obtaining a SMC product at enhanced resolution (0.1° × 0.1°) and improved ...

Resolving the Physical Ambiguity of Passive Infrared Cloud Optical Thickness Retrievals With Microwave Observations

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Satellite thermal infrared (TIR) observations, combined with machine‐learning methods, enable nighttime retrievals of cloud optical thickness (COT), but their cloud‐top‐dominated radiances provide ambiguous information for optically thick clouds.

Toward Higher Resolution Arctic Winter Sea Ice Concentration: Addressing Sentinel-1 Misclassification With AMSR2 Data Fusion

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Accurate and high-resolution sea ice concentration (SIC) products are needed for operational forecasting and climate monitoring. Passive microwave sensors, such as the advanced microwave scanning Radiometer 2 (AMSR2), provide daily SIC observations at 5 ...

Authigenic Be Isotopes Record Circumpolar Deep Water Inflow and Subglacial Outflow in Antarctic Shelf Sediments

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract The Antarctic Ice Sheet (AIS) has recently undergone accelerating mass loss driven primarily by basal melting associated with Circumpolar Deep Water (CDW) inflow onto the continental shelf. However, temporal variability in CDW inflow and its role in mass loss from the AIS over longer timescales remain uncertain because the duration of the ...

The Role of Assimilating Deep Learning‐Enhanced AMSR‐E/2 Observations in European Soil Moisture Reanalysis

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Soil moisture is an essential climate variable that controls the exchange of water and energy between land and atmosphere, directly impacting land surface feedbacks. Satellite‐derived soil moisture provides valuable large‐scale information, but long‐term applications are limited by sensor lifespans, retrieval noise, and systematic biases ...

Snow What? Strengths and Limitations of Different Snow Products in Western U.S. Mountains

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Reported values of average annual peak snow water equivalent (SWE) in the mountains of the western United States differ by more than a factor of five, from not enough water to fill Lake Mead, the largest reservoir in the region, to enough water to fill Lake Mead five times. These products are not created equal.

Beyond SMAP: Can GNSS‐R Platforms Ensure Continuity of Global Soil Moisture Observations?

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract The absence of a definitive follow‐on strategy for the Soil Moisture Active Passive (SMAP) mission, which has already surpassed its planned mission lifetime, presents a significant challenge for the hydrological science community. GNSS‐Reflectometry (GNSS‐R), which exploits reflected satellite navigation signals, has emerged as a rapidly ...
