Generation of Meteorological Parameters for Tropospheric Delay on GNSS Signal [PDF]

Journal of Astronomy and Space Sciences, 2008
The GNSS (Global Navigation Satellite System) signal is delayed by the neutral atmosphere at the troposphere, so that the delay is one of major error sources for GNSS precise positioning. The tropospheric delay is an integrated refractive index along the

Stratospheric Circulation in the Southern Hemisphere: Links to Tropical Winds, Ozone, and the Hunga Eruption—Part 1: Evidence From ERA5 Reanalysis

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract The interannual variability of the Southern Hemisphere polar vortex plays a key role in ozone depletion and recovery but this variability and its teleconnection patterns are less understood than in the Northern Hemisphere. Using ERA5 reanalysis data from 1980 to 2022 (43 years), we studied the variability of the Southern Hemisphere vortex by ...

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.

3D Atmospheric Imprint of Mesoscale Eddies Driven by the Thermal Feedback in the Gulf Stream Region

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract The 3D imprint of mesoscale ocean eddies on the overlying atmosphere is investigated using coupled ocean‐atmosphere high‐resolution simulation of the Gulf Stream region, distinguishing cyclones and anticyclones. Sea surface temperature (SST) anomalies are predominantly warm for anticyclones and cold for cyclones, driving a Thermal Feedback ...

Global Multi‐Model Eddy Dissipation Rate Probability Density Functions for Clear‐Air Turbulence Under Climate Change

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Atmospheric turbulence poses a major risk to aviation, and it is expected to intensify as a response to climate change. The probability density functions (PDFs) of dozens of different clear‐air turbulence (CAT) diagnostics have been found to shift to higher values in response to climate change, consistent with strengthened vertical wind shear ...

Contrasting Effects of Turbulence on Tropical Cyclones During Landfall

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Planetary boundary layer (PBL) turbulence modulates tropical cyclone (TC) intensity through competing mechanisms: (a) frictional dissipation that weakens TCs and (b) frictional convergence that drives stronger low‐level inflow and intensifies TCs.

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.

Dependence of Neutralized Charge Amount on Meteorological Conditions in Summertime Lightning Discharges in Japan

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Lightning discharges in Gunma Prefecture, Japan, from June–September 2023 were analyzed to explore the dependence of the neutralized charge amount on cloud structures embedded in weather systems, mainly based on in situ measurements of the ground‐based electric field, radar and satellite remote sensing, and numerical simulations using a bulk ...

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 ...
