THE DETERMINATION OF ATMOSPHERIC WATER CONTENT FROM METEOROLOGICAL AND GPS DATA
Геодинамика и тектонофизика, 2016 The Global Positioning System (GPS) based on satellites and the networks of dual frequency receivers are actively used for geodetic and geophysical applications, as well as for studying the ionosphere and troposphere.

The Influence of Zenith Tropospheric Delay on PPP-RTK [PDF]
Journal of Applied Engineering Sciences, 2016 Abstract The PPP technique is more and more used in different GPS precise application. The PPP precision is related to many factors and the most important are: the number of satellites, the ambiguity resolution, the ability to model the ionospheric and tropospheric delays, solid earth and ocean tides, relativistic effects and antenna ...

Green Emissions of Atomic Oxygen at Sprite Tops Explained
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Green emissions from excited Oxygen in Sprite Tops (GhOSTs) are due to the 557 nm photons emitted from atomic oxygen (O) $(\mathrm{O})$ excited to the 1S state. In this work we compare the possible contribution of various mechanisms for excitation of O(S1) $\mathrm{O}({}^{1}S)$ under application of a lightning‐induced electric field to the ...

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Dry‐wet whiplash events profoundly impact society and the environment, yet their attribution remain poorly understood. This study reveals that the unprecedented interannual wet‐to‐dry transition (return period: 979.2 years) in South China's 1962–1963 pre‐flood season is co‐driven by internal variability and volcanic forcing.

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The atmosphere and ionosphere form a vertically coupled system in which disturbances in the lower atmosphere can modulate ionospheric variability. Using reanalysis data, ground‐based GNSS observations, and COSMIC‐2 profiles, we investigate gravity waves (GWs) generation and upward coupling during a southwest vortex (SWV) event over the Tibetan

Current and Future Changes in Earth's Outgoing Infrared Spectrum
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Hyperspectral infrared satellite observations provide an information‐rich, global record of climate mean state and change without the structural uncertainties often present satellite retrievals and reanalyses. Current and planned hyperspectral satellite missions will continuously observe changes in Earth's outgoing infrared spectrum into the ...

Correction of the Tracking Data of an Artificial Satellite Considering the Earth Atmosphere and Light Time Effects [PDF]
Journal of Astronomy and Space Sciences, 1995 We developed a S.W system to simulate the orbit tracking data as nearly equal as the real data obtained at the tracking antenna by modeling various causes that could have effects on the tracking data (range, range rate, azimuth, elevation) of an ...

Three‐Year Characterization of Boundary Layer Dynamics From GNSS Zenith Wet Delay Spectral Analysis
Atmospheric Science Letters, Volume 27, Issue 6, June 2026.Three years of GNSS zenith wet delay observations at Payerne reveal that spectral parameters—cutoff frequency α and variance σ2—capture robust seasonal cycles in boundary layer turbulence (R2 = 0.54 for α). Their inverse coupling tightens to r = −0.82 under summer convection, encoding regime‐dependent physics.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.Abstract Medium‐Scale Traveling Ionospheric Disturbances (MSTIDs) are prominent wave‐like structures in the ionosphere, with complex generation mechanisms involving both atmospheric gravity waves (GWs) and electrodynamic instabilities such as the Perkins instability (PI).
