Glacial Earthquakes and Precursory Seismicity Associated With Thwaites Glacier Calving

Geophysical Research Letters, 2020
We observe two (~MS 3) long‐period (10–30 s) seismic events that originate from the terminus of Thwaites Glacier, Antarctica. Serendipitous acquisition of satellite images confirm that the seismic events were glacial earthquakes generated during the ...

On the Origin of Summer Sporadic E Periodicities at Midlatitudes

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Summertime midlatitude sporadic E (Es) layers exhibit daily periodicities whose underlying physical causes remain to be fully identified. We investigate the origin of these periodicities by analyzing an 11‐year data set (2007–2017) comprising ionosonde measurements, FORMOSAT‐3/COSMIC radio occultation (RO) observations, and WACCM‐X neutral ...

Dust on Snow Radiative Forcing and Contribution to Melt in the Colorado River Basin

Geophysical Research Letters
In the mountainous headwaters of the Colorado River episodic dust deposition from adjacent arid and disturbed landscapes darkens snow and accelerates snowmelt, impacting basin hydrology.

Burial and Origin of Permafrost‐Derived Carbon in the Nearshore Zone of the Southern Canadian Beaufort Sea

Geophysical Research Letters, 2020
Detailed organic geochemical and carbon isotopic (δ13C and Δ14C) analyses are performed on permafrost deposits affected by coastal erosion (Herschel Island, Canadian Beaufort Sea) and adjacent marine sediments (Herschel Basin) to understand the fate of ...

Validation of Global Ionospheric Specification (GIS) Electron Density Measurements During Solar Minimum to Solar Maximum Under Quiet and Disturbed Geomagnetic Conditions

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Global Ionospheric Specification (GIS) three‐dimensional electron density profiles constructed by assimilating the line‐of‐sight total electron content (TEC) from global navigation satellite system (GNSS) radio occultation (RO) measurements by FORMOSAT‐7/COSMIC‐2 (F7/C2) and ground‐based receiver network from international GNSS service ...

Microphysical Characteristics of Tropical Cyclone Choiwan (2021) Outer Rainbands Derived From Polarimetric Radar Observations on a Research Vessel

Geophysical Research Letters
Microphysical characteristics of tropical cyclones (TCs) over the open ocean remain elusive due to observation constraints. In this study, dual‐polarization observations derived from a ship‐borne C‐band polarimetric radar are utilized to investigate the ...

Are Elevation and Open‐Water Conversion of Salt Marshes Connected?

Geophysical Research Letters, 2020
Salt marsh assessments focus on vertical metrics such as accretion or lateral metrics such as open‐water conversion, without exploration of how the dimensions are related.

Quasi 6‐Day Wave Variability in the Thermosphere and Ionosphere: Observations and Modeling

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Satellite observations of the upper mesosphere and lower thermosphere from TIMED‐SABER and ICON‐MIGHTI reveal a clear Quasi 6‐Day Wave (Q6DW) event in the winds and temperatures in this region. This Q6DW event persists across multiple data sets throughout the middle‐to‐upper thermosphere and the F‐region ionosphere, including GOLD disk ...

Statistical Scale Analyses of a Diurnal Periodicity in Auroral Kilometric Radiation, Observed by Wind/WAVES

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract The Earth's strongest natural radio emission is Auroral Kilometric Radiation (AKR), which is correlated with auroral intensity, and is a barometer for space weather. AKR is generated by the electron cyclotron maser instability, with sources on auroral field lines. Previous work on AKR and radio emissions from other planets (or stars) points to
