The Meteoritical Bulletin, No. 114

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 5, Page 942-946, May 2026.
Abstract Meteoritical Bulletin 114 contains the 1944 meteorites approved by the Nomenclature Committee of the Meteoritical Society in 2025. It includes 15 observed falls, 1336 ordinary chondrites, 213 HED, 106 carbonaceous chondrites (including 8 ungrouped), 86 lunar meteorites, 39 ureilites, 28 iron meteorites (2 ungrouped), 24 martian meteorites, 24 ...

Relatively Intense Daytime GNSS Amplitude Scintillations at Middle Latitude Linked With Multi‐Layered Strong Es Structures

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Intense Global Navigation Satellite System (GNSS) amplitude scintillations usually occur in nighttime at low latitudes due to ionospheric plasma bubble irregularities. During daytime at middle latitudes, previous studies found that the sporadic E (Es) layer could lead to GNSS amplitude scintillations, which however, is relatively weak, for ...

Radar-derived Surface Current Fields along RV METEOR cruise track M158

open access: yes
The dataset contains near surface current fields observed between September 28, 2019, and October 22, 2019. Currents were derived from radar data acquired with a Hereon X-band marine radar (Horstmann et al., 2021).

Beyond Rock Glaciers: Investigating Meltwater Contribution and Water Quality in High‐Mountain Springs From Different Landforms

open access: yesHydrological Processes, Volume 40, Issue 4, April 2026.
We investigated the water chemistry of springs from different landforms in high‐elevation Alpine catchments. Only in predisposing lithological settings, springs from landforms most likely influenced by ice had a poor water quality with high dissolved concentrations of metals.

Terrestrial ages of meteorites from the Atacama Desert (Chile) and insights into the past meteorite flux to Earth

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 4, Page 644-663, April 2026.
Abstract The Atacama Desert in Chile is characterized by its high meteorite density and old meteorite terrestrial ages. In this work, we present new terrestrial ages derived from measurements of the concentration of cosmogenic 36Cl in the metal fraction of 51 ordinary chondrites collected over a 6.8 km2 area located in the Catalina Dense Collection ...

Neutral air density variations during strong planetary wave activity in the mesopause region derived from meteor radar observations

open access: yes, 2012
Meteor radar observations of upper mesospheric/lower thermospheric winds and temperatures are suitable to investigate planetary waves in the mesosphere. Here we present a case study of the winter season 2009/2010 for two mid-latitude stations at the edge

Mesospheric and Lower Thermospheric Responses to the May 2024 Geomagnetic Storm in the Antarctic Peninsula

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We analyze the response of mean winds and semidiurnal tides (SDTs) in the mesosphere and lower thermosphere (MLT; ∼70–110 km altitude) to the May 2024 geomagnetic super storm, based on meteor radar (MR) observations from King Sejong Station (KSS; geographic: 62.22°S, 58.78°W; geomagnetic: 53.27°S, 10.88°E) in the Antarctic Peninsula.

Thousand‐Kilometer‐Scale Wavelike Undulations in Ionospheric Plasma Bubble Lifetime and Development Over Wide Longitudes

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The irregularities of ionospheric plasma bubbles (EPBs) sequentially generated over wide longitudes are expected to share similar lifetime under normal conditions. In this study, we report a special case where the EPB irregularity lifetime over wide longitudes showed a quasi‐wavelike undulation pattern with wavelength of ∼3,000 km, that is ...
