Monitoring of the Transient Sea Level Variations Associated With Hurricane‐Induced Storm Surges by GNSS‐IR

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract As global climate change intensifies, hurricane‐induced storm surges are becoming more frequent and severe. While Global Navigation Satellite System‐Interferometric Reflectometry (GNSS‐IR) is widely used to monitor sea level variations, its capability to detect rapid and extreme events remains limited.

Major Melting Event on the Ross Ice Shelf, Antarctica, Connected With Enhanced Atmospheric Turbulence

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Ross Ice Shelf (RIS) in West Antarctica experienced extensive surface melting in January 2016, driven by warm humid air transported from over the Southern Ocean. Few studies have reported increased atmospheric water vapor and turbulent mixing during this event in this region, where the availability of surface measurements is challenging ...

Effects of Warming and Stratospheric Aerosol Injection on Tropical Cyclone Distribution and Frequency: Results From a High‐Resolution Global Circulation Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract As global circulation models (GCMs) have increased in spatial resolution, more realistic tropical cyclones (TCs) and TC distributions have been simulated. Whereas prior research on TC climatologies has relied on proxies like Potential Intensity and synthetic storm models, the cyclones simulated by newer TC‐resolving GCMs can now be analyzed ...

Correcting InSAR Topographically Correlated Tropospheric Delays Using a Power Law Model Based on ERA-Interim Reanalysis

Remote Sensing, 2017
Tropospheric delay caused by spatiotemporal variations in pressure, temperature, and humidity in the lower troposphere remains one of the major challenges in Interferometric Synthetic Aperture Radar (InSAR) deformation monitoring applications.

A Dynamical Model for the Shallow‐to‐Deep Transition of Amazonian Moist Atmospheric Convection

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract The development of deep convection and the timing of storm convection initiation over land are generally poorly represented by weather and climate models, probably due to the poor representation of the interaction between shallow and deep convection.

Tropospheric delay ray tracing applied in VLBI analysis [PDF]

Journal of Geophysical Research: Solid Earth, 2014
AbstractTropospheric delay modeling error continues to be one of the largest sources of error in VLBI (very long baseline interferometry) analysis. For standard operational solutions, we use the VMF1 elevation‐dependent mapping functions derived from European Centre for Medium‐Range Weather Forecasts data.

Convective Biases in the US DOE Global Storm‐Resolving Model: Insights From Regionally Refined Simulations During the CACTI Campaign

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Accurately simulating convective processes in complex terrain remains a critical challenge for global storm‐resolving models (GSRMs). This study systematically evaluates moist convective biases in the Regionally Refined Mesh configuration of the U.S.

An initial investigation of the non-isotropic feature of GNSS tropospheric delay

Satellite Navigation
Tropospheric delay is a significant error source in Global Navigation Satellite Systems (GNSS) positioning. Slant Path Delay (SPD) is commonly derived by multiplying Zenith Tropospheric Delay (ZTD) with a mapping function.

INSAR ATMOSPHERIC DELAY MIGITIGATION BY GPS; CASE STUDY IZMIT EARTQUAKE INTERFEROGRAMS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
The Propagation delay when radar signals travel from the troposphere has been one of the major limitations for the applications of high accuracy Interferometric Synthetic Aparture Radar (InSAR).
