Role of the Diurnal Tide in Driving the Westward Phase of the Mesospheric Semiannual Oscillation Around March Equinox

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The mesospheric semiannual oscillation (MSAO) in tropical zonal‐mean zonal winds exhibits a strong westward phase around March equinox. It has been thought that the migrating diurnal tide (DW1) plays a role in the initiation of this phase because DW1 peaks around this time and satellite observations have shown it to undergo wave breaking.

First Observation of Banded Electron Cyclotron Harmonic Waves at Earth's Magnetopause

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract This letter presents the first observation of banded Electron Cyclotron Harmonic (ECH) waves by Magnetospheric Multiscale (MMS) satellites near the Earth's subsolar magnetopause. The observation shows the fundamental mode (n=1 $n=1$) and its higher harmonics (n=2 $n=2$–6), each with distinct lower and upper bands separated by a spectral gap at

A Numerical Case Study of the Papagayo Jet Effect on East Pacific Easterly Wave Development

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract This study investigates the development of an east Pacific easterly wave (EW) event in August 2019 and the effect of the Papagayo jet on its evolution. Convective‐permitting numerical simulations were conducted. These included a control experiment and a Gap‐Filled experiment with a closed mountain gap near the Gulf of Papagayo, to test the ...

Fast Retrieval of Cloud Optical Depth From Polarimetry and Multi‐Spectral Imagery That Accounts for Cloud Heterogeneity Using 3D Radiative Transfer

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract We present a method for retrieving cloud optical depth that applies 3D radiative transfer to utilize the combination of polarimetry and multi‐spectral imagery that is newly available from satellite missions such as the Plankton, Aerosol, Cloud, Ocean, Ecosystem (PACE) Mission. Due to the approximate spectral invariance of scattering by clouds,

Laser Ablation Sampling With Low‐Power Plasma: A LA‐MIP‐MS Instrument for Spaceflight

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 3, 15 February 2026.
ABSTRACT Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) and significant gas flow (> 10 L/min), rendering them unsuitable for spaceflight, as they are too resource‐intensive for planetary spacecraft.
