The Triggering Mechanisms of a Short‐Duration Local Heavy Rainstorm Event in the Tarim Basin, China

open access: yesAdvances in Meteorology, Volume 2025, Issue 1, 2025.
The Tarim basin located in the western northwest China is the largest inland basin in the world and the core component of the arid region of the Central Asia. In recent years, the frequency of heavy rain and extreme precipitation events in the Tarim basin has increased substantially.

Building Cluster Safety Risk Assessment in Slow‐Moving Landslide Areas Based on SBAS‐InSAR Deformation Monitoring

open access: yesStructural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
Slow‐moving landslides along reservoir banks often act as precursors to catastrophic failures, which could lead to significant risks to human lives and critical infrastructures. Fortunately, interferometric synthetic aperture radar (InSAR), with its wide‐area, lightweight, and all‐weather monitoring capabilities, provides a promising method for ...

Impact and implementation of higher-order ionospheric effects on precise GNSS applications [PDF]

open access: yes, 2017
High precision Global Navigation Satellite Systems (GNSS) positioning and time transfer require correcting signal delays, in particular higher-order ionospheric (I2+) terms.

Effect of phase centre variation on tropospheric delay in PPP‐AR with low‐cost global navigation satellite systems receiver and antenna

open access: yesIET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2737-2748, December 2024.
When PCV corrections are not applied, it is clear that ambiguity resolution fails to improve the accuracy of ZWD estimates. The SEPMX5 receiver consistently outperforms the UBLX9F receiver in scenarios where PCV corrections are applied. Abstract As low‐cost global navigation satellite systems receiver and antenna become increasingly prevalent for water

Trends in the AtmosphericWater Vapor Content From Ground-Based GPS: The Impact of the Elevation Cutoff Angle [PDF]

open access: yes, 2012
We used 14 years of data from 12 GPS sites in Sweden and Finland to estimate trends in the atmospheric integrated water vapor (IWV) for 8 different elevation cutoff angles, from 5° to 40°, for the observations used in the analyses.

Improving Interpolating Accuracy of Weighted Mean Temperature by Using a Novel Lapse Rate Model in Compact VMF1 Product

open access: yesEarth and Space Science, Volume 11, Issue 11, November 2024.
Abstract In GNSS (Global Navigation Satellite Systems) meteorology, the accuracy of precipitable water vapor (PWV) retrieved from the tropospheric delay of GNSS signals is affected by the conversion factor. Compact VMF1 product (known as GGOS Atmosphere data) provides high‐accuracy global grid‐wise weighted mean temperature (Tm) values, which can be ...

Spatio‐Temporal Characteristics and Variability of GNSS‐Derived Atmospheric Precipitable Water Vapor From 2010 to 2023 in Fujian Province, China

open access: yesEarth and Space Science, Volume 11, Issue 9, September 2024.
Abstract Atmospheric precipitable water vapor (PWV) is a crucial factor affecting precipitation and the atmospheric environment. To quantitatively investigate the spatio‐temporal distribution and characteristics of the PWV in Fujian, China, its diurnal and seasonal variations are analyzed based on the global navigation satellite system (GNSS) data from

Subtle Land Subsidence Elevates Future Storm Surge Risks Along the Gulf Coast of the United States

open access: yesJournal of Geophysical Research: Earth Surface, Volume 129, Issue 9, September 2024.
Abstract We developed a robust InSAR processing strategy that can effectively mitigate severe decorrelation noise in a large volume of InSAR data. We mapped the average land subsidence rate (2017–2020) over the 131,572 km2 Upper Texas and Louisiana coasts from Sentinel‐1 data, with ∼2 mm/yr accuracy based on independent GPS and tide gauge validation at
