Polar particle flux distribution and its spatial extent

open access: yesJournal of Space Weather and Space Climate, 2023
Context: The main challenge in atmospheric ionisation modelling is that sparse measurements are used to derive a global precipitation pattern. Typically this requires intense interpolation or scaling of long-term average maps.

Spacecraft potential variations of the Swarm satellites at low Earth orbital altitudes

open access: yesEarth and Planetary Physics, 2023
In this study, we provide the first detailed analysis of variations in the spacecraft potential (Vs) of the three Swarm satellites, which are flying at about 400–500 km. Unlike previous studies that have investigated extreme charging events, usually with

Analysis of the different physical mechanisms in the atypical sporadic E (Es) layer occurrence over a low latitude region in the Brazilian sector

open access: yesFrontiers in Astronomy and Space Sciences, 2023
We present a study about the atypical and spreading Sporadic E-layers (Es) observed in Digisonde data. We analyzed a set of days around space weather events from 2016 to 2018 over Cachoeira Paulista (CXP, 22.41°S, 45°W, dip ∼35°), a low-latitude ...

Why can the auroral-type sporadic E layer be detected over the South America Magnetic Anomaly (SAMA) region? An investigation of a case study under the influence of the high-speed solar wind stream

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The low-electron flux variability (increase/decrease) in the Earth’s radiation belts could cause low-energy Electron Precipitation (EP) to the atmosphere over auroral and South American Magnetic Anomaly (SAMA) regions.

E Layer Dominated Ionosphere Occurrences as a Function of Geophysical and Space Weather Conditions

open access: yesRemote Sensing, 2020
At some locations, especially in the auroral regions, the ionization of the E layer can dominate over that of the F2 layer, which is called the E layer dominated ionosphere (ELDI).

pyGPI5: A python D- and E-region chemistry and ionization model

open access: yesFrontiers in Astronomy and Space Sciences, 2022
We present a Python implementation of a D- and E-region chemistry and ionization code called pyGPI5. Particle precipitation that penetrates into the E- and D-region of the ionosphere-thermosphere causes significant enhancements of the electron density ...

The Dependence of Cold and Hot Patches on Local Plasma Transport and Particle Precipitation in Northern Hemisphere Winter

open access: yesGeophysical Research Letters, 2022
By using a database of 4,634 cold patches (high density and low electron temperature) and 4,700 hot patches (high density and high electron temperature) from Defense Meteorological Satellite Program F16 in 2005–2018 winter months (October–March), we ...

Atmospheric Effects of Magnetosheath Jets

open access: yesAtmosphere, 2022
We report effects in the upper high-latitude atmosphere related to the interaction of fast magnetosheath plasma streams, so-called jets, with the dayside magnetopause.

Toward a Next Generation Particle Precipitation Model: Mesoscale Prediction Through Machine Learning (a Case Study and Framework for Progress)

open access: yesSpace Weather, 2021
We advance the modeling capability of electron particle precipitation from the magnetosphere to the ionosphere through a new database and use of machine learning (ML) tools to gain utility from those data.
