Relative Merits of Ionosondes, Ground GNSS TEC, and Radio Occultations for Ionospheric Data Assimilation

open access: yesRadio Science, Volume 60, Issue 12, December 2025.
Abstract Ionospheric data assimilation is the art of combining imperfect data with incomplete models to estimate the state of the ionosphere. The three most common data types are ionosonde measurements, Ground‐to‐GNSS (Global Navigation Satellite System), TEC (Total Electron Content) measurements, and RO (Radio Occultation) TEC measurements.

Stratigraphy and lithosedimentological properties of subplinian eruptions from Mt. Taranaki, New Zealand, encompassed by the Ngaere and Pungarehu edifice collapses

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 722-746, December 2025.
ABSTRACT The sudden removal of large portions of a volcanic edifice through collapse can cause depressurisation in the subvolcanic magmatic system, influencing the nature of subsequent eruptions. At Mt. Taranaki, edifice failure has occurred frequently and at different timescales throughout the volcanic history, forming a broad pattern of cyclic ...

The Epidemiology, Phylogeny, and Strain Antigenicity of an Influenza A/H3N2 Virus Outbreak Among Vaccinated US Navy Midshipmen

open access: yesInfluenza and Other Respiratory Viruses, Volume 19, Issue 12, December 2025.
ABSTRACT We performed epidemiological, genetic, and antigenic characterization of an influenza A/H3N2 outbreak in a congregate setting of young adults with high vaccination rates. We noted substantial duty‐days lost, rapid spread, and vaccine antigenic divergence.
