A new model for estimating atmospheric weighted mean temperature from radiosonde and multi-mission GNSS radio occultation data

In Global Navigation Satellite System (GNSS) meteorology, the atmospheric weighted mean temperature (Tm) is a critical intermediate parameter for converting zenith wet delay (ZWD) to precipitable water...

Coseismic deformation and slip distribution of the 2025 MW7.1 Dingri earthquake constrained by GNSS and InSAR observations

On January 7, 2025, an MW7.1 earthquake struck Dingri County, Xigaze City, southern Xizang. The epicenter was located on the western side of the Dengme Co Fault (DMCF) in the southern segment of the...

Hybrid singular spectrum analysis and LSTM modeling for daily precipitation forecasting

To address the limitations of traditional univariate time series methods in achieving accurate daily precipitation forecasts, this contribution proposes a hybrid predictive model that integrates singular...

Real-time earthquake magnitude prediction using designed machine learning ensemble trained on real and CTGAN generated synthetic data

The earthquake early warning (EEW) system provides advance notice of potentially damaging ground shaking. In EEW, early estimation of magnitude is crucial for timely rescue operations. A set of thirty-four...

Review of SAR imaging geodesy for glacier velocity monitoring

The surface velocity is one of the most important characteristics of glaciers. Monitoring and mapping glacier movements are of great significance for the studies of sea-level rise, glacier mass balance...

Multi-temporal InSAR analysis for assessment of earthquake precursory deformation

Ground deformation is a key parameter in interpreting precursory stress and strain patterns and provides valuable information for seismic studies. Interferometric Synthetic Aperture Radar (InSAR) is...

Unscented Kalman filter for a low-cost GNSS/IMU-based mobile mapping application under demanding conditions

For the last two decades, low-cost Global Navigation Satellite System (GNSS) receivers have been used in various applications. These receivers are mini-size, less expensive than geodetic-grade receivers,...

Role of crustal structure in geodynamic evolution and seismogenesis in the eastern Indo-Gangetic Foreland Basin and Himalayan Collision Zone

The incessant convergence between the Indian and Eurasian plates has significantly altered the crustal thicknesses of the Indian subcontinent since their collision and formed one of the most dynamically...

Slow slip events detection algorithm based on an optimization-based signal decomposition framework: A case study in Cascadia zone

Slow Slip Events (SSEs) are critical for understanding subduction zone tectonics and earthquake prediction; however their detection is challenged by low-magnitude-offsets and data gaps. To address these...

A review of tidal triggering of global earthquakes

Earthquake prediction remains a challenging and difficult task for scientists all over the world. The tidal triggering of earthquakes is being proven by an increasing number of investigations, most...

Sea level rise in the Baltic Sea: Data from Estonian coastal tide gauges over 30 years

This study investigates the rate of sea level rise along the Estonian coastline of the Baltic Sea over the three decades (1993–2022) using tide gauge data and advanced analytical methods. Tide gauge...

Geodetic slip rate and seismogenic depth of unmapped active faults in Yogyakarta, Indonesia, inferred from dense Global Navigation Satellite System campaign observation

Yogyakarta was struck by a devastating MW6.3 earthquake, which intensified awareness about the seismic hazards in the region. This study investigates the kinematic slip rate and seismogenic depth of...

Factors controlling induced earthquakes in Oklahoma

Injection-induced earthquake (IIE) caused by human activities has become a global problem due to the increased magnitude and frequency in recent decades. However, not all injections can induce earthquakes,...

Spatial and temporal analysis of urban heat island effect over Tiruchirappalli city using geospatial techniques

Alterations made to the natural ground surface and the anthropogenic activity elevate the surface and air temperature in the urban areas compared with the surrounding rural areas, known as urban heat...

A navigation method for IMU/odometer fusion based on horizontal attitude constraints

The current inertial measurement unit (IMU) and odometry fusion navigation algorithms often incorporate non-holonomic constraints (NHC) to obtain three-dimensional velocity in the navigation frame....
