Using Ionosondes for Lower‐Ionosphere Remote Sensing

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Ionosondes are primarily used to measure the electron densities of the ionosphere's E and F‐region via frequency‐range analysis of the probing signal returns. The amplitude of the returning signal has often been ignored, however, and may allow estimates of other propagation effects such as D and E‐region absorption.

Ice‐Nucleating Particles Are Emitted by Raindrop Impact

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 11, 16 June 2025.
Abstract Ice‐nucleating particles (INPs) play a key role in ice formation and cloud microphysics and thus significantly impact the water cycle and the climate. However, our understanding of atmospheric INPs, particularly their sources, emissions, and spatiotemporal variability, is incomplete. While the enhancement of atmospheric INP concentrations with

Aerosol and Meteorological Influences on Mixed‐Phase Stratiform Clouds at North Slope of Alaska

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Uncertainty in estimates of Arctic Amplification is largely sensitive to the simulation of Arctic clouds in climate models. Mixed‐phase stratiform clouds are of particular interest due to their ubiquity in the Arctic. Here, we present a new long‐term data set composed of various observations specifically designed to identify cloud controlling ...

Nature, origin and significance of a clayey cave deposit: Relationship between karst and Oligocene/Miocene tephra (NW Dinarides)

The Depositional Record, Volume 11, Issue 3, Page 954-974, June 2025.
A limestone cave in the NW Dinarides exhibits an anomalous presence of montmorillonite clay, not commonly found in surrounding caves, posing questions about its origin and age. Analysis reveals a composition similar to weathered tephra from the Smrekovec Volcanic Complex, suggesting transport by north‐east winds.
