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 ...

How Well Is the Lake‐Land Breeze Circulation of Lake Victoria Captured in ECMWF Operational Analysis?

Atmospheric Science Letters, Volume 27, Issue 8, August 2026.
Lake‐breeze fronts (LBFs) strongly influence cloudiness, deep convection, and heavy rainfall around tropical lakes, yet their representation in global forecast systems remains uncertain. Using a newly developed objective detection algorithm, we evaluate LBF evolution and timing in ECMWF forecasts.

Independent Component Analysis (ICA) as a Superior Atmospheric Correction Method for InSAR Time Series

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Satellites such as the European Space Agency's Sentinel‐1 constellation allow for the creation of unprecedented volumes of Interferometric Synthetic Aperture RaDAR data that contains both deformation and atmospheric signals. Correction methods have been developed to reduce these atmospheric signals, but they do not generally perform well on ...

Agricultural Emissions of Reactive Nitrogen Gases From Constrained Simulations Using the Community Land Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract Reactive nitrogen (Nr) gases (NH3, N2O, and NO) emitted from agricultural fields constitute a substantial portion of the Nr flux from land to the atmosphere. Here, we coupled the Flows of Agricultural Nitrogen (FANv3) with a modified version of the Community Land Model (CLM5.1) to produce a model (CLM‐FANv3) that simulates the emissions of NH3,

Error Growth Characterization Associated With Lateral Boundary Conditions in Idealized Moist Baroclinic Wave Simulations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract This study investigates numerical error growth mechanisms associated with lateral boundary conditions (LBCs) and their sensitivity to update frequency within a “Big‐Brother” framework. Using an idealized moist WRF baroclinic wave simulation, a high‐resolution reference is compared against three nested configurations: traditional one‐way 6‐hr ...

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 ...

Tertiary‐Ozone‐Maximum‐Like Mesospheric Ozone Increases Driven by Solar Eclipses: Sensitivity Experiments on WACCM‐X

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Solar eclipses offer natural experiments to isolate the photochemical response of mesospheric ozone to solar radiation. Using the WACCM‐X model, we performed mechanism‐oriented sensitivity experiments for the 14 December 2020 eclipse to quantify the tertiary‐ozone‐maximum‐like (TOM‐like) response.

Empirical modeling of tropospheric delays with uncertainty

Geoscientific Model Development
Abstract. Accurate modeling of tropospheric delay is important for high-precision data analysis of space geodetic techniques, such as the Global Navigation Satellite System (GNSS). Empirical tropospheric delay models provide zenith delays with an accuracy of 3 to 4 cm globally and do not rely on external meteorological input.
