Influence of Ionospheric Irregularities on GNSS Remote Sensing

Advances in Meteorology, 2015
We have used numerical simulation to study the effects of ionospheric irregularities on accuracy of global navigation satellite system (GNSS) measurements, using ionosphere-free (in atmospheric research) and geometry-free (in ionospheric research) dual ...

GNSS Meteorology in Luxembourg

, 2012
Atmospheric water vapour is a primary greenhouse gas and plays an important role in weather forecasting and climate monitoring. Global Navigation Satellite System (GNSS) signals experience a propagation delay, which is related to the amount of water vapour in the lower atmosphere.

Are Estimates of Wind Characteristics Based on Measurements with Pitot Tubes and GNSS Receivers Mounted on Consumer-grade Unmanned Aerial Vehicles Applicable in Meteorological Studies? [PDF]

, 2017
The objective of this paper is to empirically show that estimates of wind speed and wind direction based on measurements carried out using the Pitot tubes and GNSS receivers, mounted on consumer-grade unmanned aerial vehicles (UAVs), may accurately ...

Vertical Land Motion and Human Exposure Across India's Coastal Regions

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract In India, over 200 million people live within 100 km of the coastline, and many reside in low‐lying areas exposed to increasing flood risks associated with sea‐level rise. However, the role of vertical land motion (VLM)—particularly land subsidence—in shaping this coastal exposure remains poorly quantified. Here we present the first assessment

A Continuum of Slow Slip Events in the Cascadia Subduction Zone Illuminated by High‐Resolution Deep‐Learning Denoising

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Slow, aseismic fault slip has emerged as a significant contributor to the seismic cycle. However, whether slow and fast slip arise from similar physical processes remains unresolved, due to detection biases affecting noisy surface measurements and the analysis of the source properties of slow slip.

Abrupt Along‐Strike Change of Shallow Seismicity in Central and Southern Myanmar: Insights From High‐Resolution Local‐Earthquake Catalogs and Focal Mechanisms

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Myanmar's high seismic hazard is underscored by the 2025 Mw 7.7 earthquake on the Sagaing Fault, yet its seismicity patterns and underlying controls remain poorly understood. Using new seismic data from the 2nd‐phase array of the China‐Myanmar Geophysical Survey in the Myanmar Orogen, we construct a high‐resolution catalog of 1,819 local ...

Migration of Multimodal Deep Crustal Earthquake Swarm Beneath the Abu Volcano Group, Japan

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquakes in the lower crust, where high pressures and temperatures favor ductile deformation, are rare but occasionally occur beneath active volcanic centers, providing insights into deep magmatic processes. We analyze a deep crustal earthquake swarm (February–August 2025) of over 5,000 events beneath the Abu Volcano Group, Japan.

The Potential for Observing African Weather with GNSS Remote Sensing

Advances in Meteorology, 2015
When compared to the wide range of atmospheric sensing techniques, global navigation satellite system (GNSS) offers the advantage of operating under all weather conditions, is continuous, with high temporal and spatial resolution and high accuracy, and ...

Measuring the Water Level Datum Relative to the Ellipsoid During Hydrographic Survey [PDF]

, 2011
Hydrographic surveys are referenced vertically to a local water level “chart” datum. Conducting a survey relative to the ellipsoid dictates a datum transformation take place before the survey is used for current navigational products.
