Preliminary study of GNSS meteorology techniques in Algeria

International Journal of Remote Sensing, 2013
Algeria 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, 2022
Aerosol 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, 2007
Earth 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 Technology
Abstract 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.

GNSS Meteorology: AI-Enabled Assimilation of GNSS-derived Tropospheric Parameters with Two Demonstrated Case Studies

GNSS Meteorology is an increasingly important source of atmospheric observations, providing near-real-time information on tropospheric water vapor derived from GNSS signal delays. These observations become especially valuable when available at high density, enabling improved characterization of mesoscale moisture gradients and rapidly evolving ...
