Validation of Soil Temperature Sensing Depth Estimates Using High-Temporal Resolution Data from NEON and SMAP Missions

Remote Sensing
Passive microwave remote sensing of soil moisture is crucial for monitoring the Earth’s water cycle and surface dynamics. The penetration depth during this process is significant, as it influences the accuracy of retrieved soil moisture data.

Rock Physics of the Critical Zone: Models, Inversion, and Interpretation

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Rock physics models link geophysical measurements with subsurface petrophysical properties, such as porosity, mineral composition, and fluid saturation. While originally developed for hydrocarbon exploration, these models are increasingly applied in the near surface for quantitative interpretation of geophysical data.

The Influence of Sea Ice and Ice Mélange on Outlet Glacier Dynamics in the Arctic and Antarctic: Recent Progress and Future Challenges

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Sea ice is situated close to the termini of many outlet glaciers in the Arctic and Antarctic and has the potential to influence their dynamics and, therefore, their contribution to sea level rise. However, the nature, prevalence, and ice‐dynamic significance of sea ice‐glacier interactions remains subject to several open questions.

Frequency Standard Contributions to Limitations on the Signal‐to‐Noise Ratio in Very Long Baseline Interferometric Observations

Radio Science, Volume 61, Issue 6, June 2026.
Abstract Since its observation in 2019, the first image of a super‐massive black hole using Very Long Baseline Interferometry (VLBI) with an Earth‐scale baseline has generated much scientific and public interest. Work is now underway to extend the baseline into space to obtain higher image resolution.

A Comparative Analysis of Remote Sensing Soil Moisture Datasets Fusion Methods: Novel LSTM Approach Versus Widely Used Triple Collocation Technique

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Microwave remote sensing technology has emerged to provide valuable products to monitor and assess soil moisture content at regional or global scales. However, each soil moisture product exhibits different advantages and shortcomings.

New High Precision Measurements of Apollo Samples: 0.3–5 GHz Complex Refractive Indices

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Active and passive radar techniques provide information on the subsurface structure and history of planetary bodies. However, interpretations of radar data are limited by our understanding of the complex dielectric permittivity and magnetic permeability of the surface material.

Physically Consistent Synthesis of Tropical Cyclone Microwave Brightness Temperatures From Geostationary Infrared Observations

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Analyzing the evolution of Tropical Cyclones (TCs) is critical for understanding their structure and intensity, but it has been limited by observational constraints. Spaceborne passive microwave (PMW) observations can penetrate both non‐precipitating and precipitating clouds and provide information on the vertical distribution of hydrometeors ...

Running an electron microscopy core facility

Journal of Microscopy, Volume 302, Issue 3, Page 346-357, June 2026.
Abstract As electron microscopes became more costly, technically complex, and integral to a wide range of scientific fields, centralised electron microscopy (EM) core facilities have become essential for maintaining accessibility, performance, and quality.

Snow Depth on Arctic Sea Ice Retrieval Using a Synergy of Sentinel‐3's Active and Passive Microwave Instruments

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Snow depth remains one of the largest sources of uncertainty in satellite‐derived sea ice thickness (SIT). Here, we introduce the novel Nadir Radiometer and Radar Synergy (NaRRS) method that combines data from Sentinel‐3's Microwave Radiometer (MWR) and Synthetic Aperture Radar Altimeter (SRAL) to retrieve Arctic snow depth on sea ice.

A First Attempt at Reconstructing FengYun‐4B Stratified Precipitable Water Using GNSS

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Layer Precipitable Water (LPW) characterizes the vertical structure of atmospheric moisture and is essential for accurate weather forecasts. China's FY‐4B satellite delivers near‐real‐time LPW products, but is constrained by large uncertainties.
