IMPACT OF IONOSPHERIC HORIZONTAL ASYMMETRY ON ELECTRON DENSITY PROFILES DERIVED BY GNSS RADIO OCCULTATION [PDF]

open access: yes, 2013
The ‘Onion-peeling' algorithm is a very common technique used to invert Radio Occultation (RO) data in the ionosphere. Because of the implicit assumption of spherical symmetry for the electron density distribution in the ionosphere, the standard Onion ...

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.

Climate-Driven Cryospheric Changes and Their Impacts on Glacier Runoff Dynamics in the Northern Tien Shan

open access: yesAtmosphere
Glaciers in the Northern Tien Shan are a major source of Ile River runoff, supplying water to Kazakhstan’s largest city, Almaty. Under ongoing climate warming, their degradation alters the magnitude and seasonality of river discharge, increasing water ...

A possible effect of atmospheric circulation in the daily variation of the earth's magnetic field [PDF]

open access: yes, 1963
The daily variation of the horizontal intensity of the earth's magnetic field at Honolulu exhibits seasonal features that are not related in a simple way to solar declination.

Atmospheric Ion‐Neutral Coupling as a Potential Driver for Saturn's Magnetospheric Antisunward Electric Field

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Saturn's inner magnetosphere contains a weak antisunward electric field that has influenced a wide array of different aspects of the magnetospheric conditions in that region. Previously, these currents have been explained as being caused by magnetospheric drivers.

Observation of the Large Forbush Decrease Event on 1–10 June 2025 at the Tien Shan Cosmic Ray Station

open access: yesAtmosphere
An intensive disturbance of the heliosphere originating from a series of solar flares at the end of May 2025 revealed itself as an extremely strong Forbush decrease in the flux of galactic cosmic rays, which was observed at the worldwide network of ...

The International Reference Ionosphere - A Model Ionosphere

open access: yesEos, 2023
An accurate and reliable description of Earth’s ionosphere is of critical importance because of our increased reliance on satellite technology and the significant impact the ionosphere has on it.

Effects of electrojet turbulence on a magnetosphere-ionosphere simulation of a geomagnetic storm [PDF]

open access: yes, 2017
Ionospheric conductance plays an important role in regulating the response of the magnetosphere‐ionosphere system to solar wind driving. Typically, models of magnetosphere‐ionosphere coupling include changes to ionospheric conductance driven by extreme ...

Response of the Migrating Solar Semidiurnal Tide to Arctic and Antarctic Stratospheric Polar Vortices: A Comprehensive Study

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract In this study, we use the Specified Dynamics Whole Atmosphere Community Climate Model with thermosphere‐ionosphere eXtension (SD‐WACCM‐X) to investigate how the migrating solar semidiurnal tide (SW2) in the mesosphere and lower thermosphere (MLT) responds to the strength of Arctic and Antarctic Stratospheric Polar Vortices (SPVs).

Influence of the hypermagnetic field noise on the baryon asymmetry generation in the symmetric phase of the early universe

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We study a matter turbulence caused by strong random hypermagnetic fields (HMFs) that influence the baryon asymmetry evolution due to the Abelian anomalies in the symmetric phase in the early Universe.
