Atmospheric dispersion and the implications for phase calibration [PDF]
, 2009 The success of any ALMA phase-calibration strategy, which incorporates phase transfer, depends on a good understanding of how the atmospheric path delay changes with frequency (e.g. Holdaway & Pardo 2001).

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 ...

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Previous observations have demonstrated that rocket exhaust can trigger ionospheric electron density holes and cause electron temperature enhancements during launches. Using high‐precision measurements from the Sanya incoherent scatter radar, we discovered a previously overlooked decrease in electron temperature.

Kernel‐Based Estimation of Stratospheric Aerosol Radiative Effects From Volcanic and Wildfire Events
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.Abstract To facilitate the quantification of the stratospheric aerosol direct radiative effect (ARE), this study develops a suite of aerosol kernels based on Modern‐Era Retrospective Analysis for Research and Applications, Version 2 reanalysis data. The kernels comprise a five‐dimensional data set that includes latitude, longitude, time, wavelength ...

An Analytical Model of the Lifecycle of Tropical Anvil Cloud Radiative Effects
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.Abstract Satellite observations and numerical simulations show that the small net Cloud Radiative Effect (CRE) of tropical anvil clouds results from a near‐cancellation between large but opposing longwave (LW) and shortwave (SW) components over the cloud's lifecycle.

Impact of a high density GPS network on the operational forecast [PDF]
Advances in Geosciences, 2005 Global Positioning System Zenith Total Delay (GPS ZTD) can provide information about the water vapour in atmosphere. Its assimilation into the analysis used to initialize a model can then improve the weather forecast, giving the right amount of moisture ...

Mesoscale GPS Zenith Delay assimilation during a Mediterranean heavy precipitation event [PDF]
Advances in Geosciences, 2008 The impact of assimilating Zenith Total delay (ZTD) observations from a mesoscale ground-based GPS network over Western Europe is evaluated for the heavy precipitation event of 5–9 September 2005 over Southern France.
