Initial Atmospheric Waves Experiment (AWE) Imaging Analyses: Gravity Wave Sources, Temperatures, Pseudomomentum Fluxes, and Horizontal Wavenumber Spectra at the OH Layer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The NASA Atmospheric Waves Experiment (AWE) employs an OH imager that began measurements aboard the International Space Station (ISS) on 22 November 2023. The motivation for AWE was to quantify gravity wave (GW) responses to diverse sources and their influences extending into the mesosphere and higher altitudes.

Nanometric Faujasite (FAU) Zeolite Ion‐Exchanged With Metal Ions for Hemostatic and Antimicrobial Applications: A Thromboelastographic and Microbiological Study

Chemistry – An Asian Journal, Volume 21, Issue 9, 14 May 2026.
Faujasite nanozeolite (NanoFAU) and its ion‐exchanged forms (Ag+, Ba2+, Ca2+, Mg2+) were synthesized and characterized to assess their biomedical potential. NanoFAU‐Ca showed superior hemostatic activity, while NanoFAU‐Ag exhibited strong antimicrobial effects against S. aureus and C. albicans.

Intraseasonal oscillation (ISO) in the MLT zonal wind over Kolhapur (16.8° N) and Tirunelveli (8.7° N) [PDF]

Annales Geophysicae, 2012
Simultaneous observations of the mean zonal winds at 88 km obtained by the medium-frequency (MF) radars at Kolhapur (16.8° N, 74.2° E) and Tirunelveli (8.7° N, 77.8° E) have been used to study the intraseasonal oscillation (ISO) in the MLT region. The

Characterizing the ionospheric current pattern response to southward and northward IMF turnings with dynamical SuperMAG correlation networks

, 2017
We characterize the response of the quiet time (no substorms or storms) large-scale ionospheric transient equivalent currents to north-south and south-north IMF turnings by using a dynamical network of ground-based magnetometers.

Atomic oxygen number densities in the MLT region measured by solid electrolyte sensors on WADIS-2

, 2018
. Absolute profiles of atomic oxygen number densities with high vertical resolution have been determined in the MLT region from in-situ measurements by several rocket-borne solid electrolyte sensors.

Dissipation Rates of Mesospheric Stratified Turbulence From Multistatic Meteor‐Radar Observations

Geophysical Research Letters
Stratified turbulence (ST) has been proposed as a model for the dynamics of the mesosphere‐lower thermosphere (MLT) region. This theory postulates that for horizontal mesoscales (∼1–400 km), the kinetic energy of horizontal winds dissipates from large to

Competing source and loss mechanisms due to wave-particle interactions in Earth’s outer radiation belt during the 30 September to 3 October 2012 geomagnetic storm [PDF]

, 2014
Drastic variations of Earth’s outer radiation belt electrons ultimately result from various competing source, loss, and transport processes, to which wave-particle interactions are critically important.

Solar Wind‐Magnetosphere‐Ionosphere Coupling During the October 2024 Storms

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Two geomagnetic storms occurred in October 2024 (Oct 6‐9 and 10–12), driven by the impact of a series of interplanetary coronal mass ejections on the magnetosphere. The first was a moderate storm, with peak Sym‐H near −150 nT, whereas the second was intense, Sym‐H reaching −340 nT.

Seasonal MLT-region nightglow intensities, temperatures, and emission heights at a Southern Hemisphere midlatitude site

, 2017
. We consider 5 years of spectrometer measurements of OH(6–2) and O2(0–1) airglow emission intensities and temperatures made near Adelaide, Australia (35° S, 138° E), between September 2001 and August 2006 and compare them with measurements of the same ...
