Orographic and convective gravity waves above the Alps and Andes mountains during GPS radio occultation events – a case study [PDF]

open access: yes, 2017
The significant distortions introduced in the measured atmospheric gravity wavelengths by soundings other than in vertical and horizontal directions, are discussed as a function of elevation angle of the sounding path and the gravity waves aspect ratio ...

Monitoring Flood Inundation Dynamics From Space

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract With the increasing intensity and frequency of flood events worldwide, the need for accurate and timely inundation mapping has never been more critical. Large‐scale flood extent estimations are vital for coordinating effective disaster response, facilitating recovery, and building future resilience.

Tropospheric delays in ground-based GNSS Multipath Reflectometry – experimental evidence from coastal sites [PDF]

open access: yes, 2017
Recent studies have demonstrated the utility of ground based GNSS Multipath Reflectometry (GNSS-MR) for sea level studies. Typical root-mean-square (RMS) differences of GNSS-MR derived sea level time series with respect to nearby tide gauges are on the ...

Quantifying the Impacts of the May 2024 Geomagnetic Storm on Transatlantic Aviation: Rerouting, Delays, and Economic Losses

open access: yesSpace Weather, Volume 24, Issue 3, March 2026.
Abstract The May 2024 geomagnetic storm, one of the most intense events of Solar Cycle 25 to date, caused widespread disruptions in aviation operations, particularly for polar and high‐latitude routes. This study quantifies the operational and economic impacts of the storm on 12 selected transatlantic flights between North America and Europe.

Global Bottomside Ionospheric Modeling Based on GNSS‐RO Observations From the Tianmu‐1 Constellation

open access: yesSpace Weather, Volume 24, Issue 3, March 2026.
Abstract Radio occultation (RO) observations provide a crucial means for estimating the global Vertical Bottomside Electron Content (VBEC) in the ionosphere. However, the limited number of low Earth orbit (LEO) satellites in existing RO missions restricts the capability for high‐precision reconstruction of global VBEC spatiotemporal variations.

GNSS troposphere tomography based on two-step reconstructions using GPS observations and COSMIC profiles [PDF]

open access: yes, 2013
Traditionally, balloon-based radiosonde soundings are used to study the spatial distribution of atmospheric water vapour. However, this approach cannot be frequently employed due to its high cost. In contrast, GPS tomography technique can obtain water
