The Effects of Meteorological Parameters on GNSS Height Component
2023In this study, when the height components of continuous GNSS stations were examined, it was seen that there were seasonal effects, and it was investigated whether the height components were related to meteorological parameters. Linear regression analysis was performed to obtain how dependent the height components of the continuous GNSS stations were on

Real-Time GNSS Meteorology in Europe - Hurricane Lorenzo Case Study
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021Near real-time estimation of zenith total delays (ZTD) of Global Navigation Satellite Systems (GNSS) signals is operationally performed in Europe. We demonstrate that high accuracy ZTD can be provided even in real-time. Using a state-of-the-art processing strategy we estimate ZTD and horizontal gradients for 162 permanent stations in Europe over 100 ...

Preliminary study of GNSS meteorology techniques in Algeria
International Journal of Remote Sensing, 2013Algeria is still not covered by the global navigation satellite system GNSS permanent stations network, despite its advantages as a novel technology for environmental development and strategy. The work presented here aims to show a preliminary study of GNSS meteorology techniques in Algeria.

Adaptive AOD Forecast Model Based on GNSS-Derived PWV and Meteorological Parameters
IEEE Transactions on Geoscience and Remote Sensing, 2022Aerosol optical depth (AOD) is one of the basic parameters for determining the total aerosol content, and it exerts an important impact on regional environment pollution. To investigate the spatiotemporal variations of AOD, this study analyzes the relationship of AOD with precipitable water vapor (PWV) derived from a global navigation satellite system (

An Evaluation of GNSS Radio Occultation Technology for Australian Meteorology
Journal of Global Positioning Systems, 2007Earth atmospheric information has been primarily observed by a global network of radiosonde weather observation stations for global weather forecasting and climatologic studies for many years. However, the main disadvantage of this method is that it can not sufficiently capture the complex dynamics of the Earth’s atmosphere since its limited and ...

Spatiotemporal-varying tropospheric stochastic model for GNSS meteorology enhancement
Measurement Science and TechnologyAbstract Accurately estimating the zenith wet delay (ZWD) is critical in Global Navigation Satellite System (GNSS) meteorology. ZWD is typically modeled as a random walk process with spatiotemporal-invariant process noise in the Kalman filter using precise point positioning.
