Capturing Extreme Water Vapor and Instability With High‐Resolution GNSS Monitoring

Atmospheric Science Letters, Volume 27, Issue 2, February 2026.
This study used data from a high‐resolution Global Navigation Satellite System network (< 10 km spacing), including private stations, to analyze water vapor structure during a heavy rainfall event in Japan. The network captured localized extreme precipitable water vapor (> 70 mm) and a moist absolutely unstable layer near the humid core.

Water Vapor Vertical Distribution on Mars After Six Years of TGO/NOMAD Solar Occultations: 1. Global Climatology

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract We present vertical profiles of water vapor obtained during six continuous years of solar occultation observations in the infrared by the Nadir and Occultation for MArs Discovery (NOMAD) instrument on board Trace Gas Orbiter. The retrievals have been performed with an inversion code previously applied to smaller samples of this data set, but ...

A Novel Robust High‐Precision Ionospheric Delay Modeling for PPP‐RTK Using Crowdsourced Data

Space Weather, Volume 24, Issue 2, February 2026.
Abstract The performance of PPP‐RTK is critically dependent on the quality of ionospheric corrections derived from a reference network. While the proliferation of mass‐market Global Navigation Satellite System (GNSS) devices offers a promising crowdsourcing opportunity to densify or replace this infrastructure, it introduces the formidable challenge of

Atmospheric Water Vapor and Precipitation Coupling in Southwestern South America

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Most studies linking atmospheric water vapor and precipitation emphasize short records, tropical regions, or the Northern Hemisphere. Long‐term variability of water vapor and its coupling with precipitation remain poorly understood across strong latitudinal and climatic gradients.

Distance to G14.33-0.64 in the Sagittarius Spiral Arm: H2O Maser Trigonometric Parallax with VERA

, 2010
We report on trigonometric parallax measurements for the Galactic star forming region G14.33-0.64 toward the Sagittarius spiral arm. We conducted multi-epoch phase-referencing observations of an H2O maser source in G14.33-0.64 with the Japanese VLBI ...

Impact of atmospheric parameters on the atmospheric Cherenkov technique [PDF]

, 1999
Atmospheric density profiles as well as several light absorption and scattering processes depend on geographic position and are generally time-variable.

Horseshoe‐Shaped Vortices Accompanied With Breaking of Upward Propagating Gravity Waves and Their Relation to Mean‐Flow Acceleration

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.
Abstract Breaking gravity waves (GWs) are a major source of turbulence and momentum deposition in the middle atmosphere. In spite of the importance of this phenomenon, the small‐scale vortex structures associated with wave breaking remain poorly documented under realistic conditions.

Radio Astrometry Of The Triple Systems Algol And UX Arietis

, 2011
We have used multi-epoch long-baseline radio interferometry to determine the proper motion and orbital elements of Algol and UX Arietis, two radio-bright, close binary stellar systems with distant tertiary components.

Tropospheric NO2 Patterns in Eastern Canada Using the First Year of TEMPO Observations

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.
Abstract The Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument enables an unprecedented assessment of diurnal and community‐scale variations in tropospheric nitrogen dioxide (NO2) across North America. This study presents the first exploratory analysis of NO2 patterns in eastern Canada, including Ontario, Quebec, and the Atlantic ...

Precise estimation of tropospheric path delays with GPS techniques [PDF]

Tropospheric path delays are a major source of error in deep space tracking. However, the tropospheric-induced delay at tracking sites can be calibrated using measurements of Global Positioning System (GPS) satellites.
