A zenith tropospheric delay correction model based on the regional CORS network

Geodesy and Geodynamics, 2012
Tropospheric delay is a primary error source in earth observations and a variety of radio navigation technologies. In this paper, the relationship between zenith tropospheric delays and the elevation and longitude of stations is analyzed using the zenith

Transport to the Extratropical Stratosphere by Overshooting Storms in Idealized Simulations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Deep convection is a significant source of water to the extratropical stratosphere which can alter radiative properties and contribute to ozone loss. Previous studies find it responsible for 40% of mid‐latitude water vapor above 380K. However, the amount of hydration from individual storms and the mechanisms that initiate mixing is less ...

Rapid Land Surface Uplift and Groundwater Recovery Observed During the Syrian War

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Recent geopolitical upheaval in Syria is driving regional growth by returning populations, which increases demands on water resources. In northwest Syria, widespread cropland abandonment during the Syrian War starting in 2011 drastically changed the hydrological regime of the region.

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.

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.

Roles of Surface Latent Heat Flux and Gravity Waves in Offshore MCS Development in the Coastal Eastern Tropical Pacific

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The eastern tropical Pacific (ETP) coastal region, one of the rainiest places on Earth, is characterized by distinct diurnal offshore rainfall propagation primarily driven by mesoscale convective systems (MCSs). Previous studies have shown that MCS initiation in this region peaks in the early morning, with diurnally generated gravity waves ...

Progress in Measurements of the Gravitational Bending of Radio Waves Using the VLBA [PDF]

, 2009
We have used the Very Long Baseline Array (VLBA) at 43, 23 and 15 GHz to measure the solar gravitational deflection of radio waves among four radio sources during an 18-day period in October 2005.

Modeling and Modification of Global Positioning System Tropospheric Delay Mapping Function [PDF]

, 2008
The accuracy of Global Positioning System (GPS) measurement is determined by the sum of several sources of error, such as orbit error, satellite clock error, multipath error, receiver noise error, selective availability, ephemeris error and also ...

Simulations of a High Ozone Episode and Heatwave Day Using a Coupled Multi‐Layer Urban Canopy and Chemistry Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Coastal cities face critical challenges in managing ozone pollution because of high population density and complex interactions between urbanization and coastal meteorology. Using New York City (NYC) as a case study, this work examines how urban surfaces influence heatwaves, sea‐breeze circulations, and boundary‐layer dynamics, and how these ...

A Graph Signal Processing Approach to the Characterization of Xe‐133 Atmospheric Background

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract The geopolitical context advocates for monitoring nuclear activities within an international framework. In this context, the Comprehensive Nuclear‐Test‐Ban Treaty Organization has established measurement stations, known as the International Measurement System (IMS).
