Knobs and dials of retrieving JWST transmission spectra. II. Impacts of pipeline-level differences on retrieval posteriors
Simon Schleich, Sudeshna Boro Saikia, Quentin Changeat +3
Since the launch of JWST, observations of exoplanetary atmospheres have seen a revolution in data quality. Given that atmospheric parameter inferences depend heavily on the underly…
Knobs and dials of retrieving JWST transmission spectra. I. The importance of p-T profile complexity
Simon Schleich, Sudeshna Boro Saikia, Quentin Changeat +3
We investigate the impact of using multipoint p-T profiles of varying complexity on the retrieval of synthetically generated hot Jupiter transmission spectra modelled after state-o…
Which Upstream Solar Wind Conditions Matter Most in Predicting Bz within Coronal Mass Ejections
Pete Riley, M. A. Reiss, C. Mostl
Accurately predicting the z-component of the interplanetary magnetic field, particularly during the passage of an interplanetary coronal mass ejection (ICME), is a crucial objectiv…
Automatic Detection of Interplanetary Coronal Mass Ejections in Solar Wind In Situ Data
Hannah T. Rüdisser, Andreas Windisch, Ute V. Amerstorfer +4
Interplanetary coronal mass ejections (ICMEs) are one of the main drivers for space weather disturbances. In the past, different approaches have been used to automatically detect e…
Writhed Analytical Magnetic Flux Rope Model
Andreas J. Weiss, Teresa Nieves-Chinchilla, Christian Möstl +3
Observations of magnetic clouds, within interplanetary coronal mass ejections (ICMEs), are often well described by flux rope models. Most of these assume either a cylindrical or to…
Forecasting GICs and geoelectric fields from solar wind data using LSTMs: application in Austria
R. L. Bailey, R. Leonhardt, C. Möstl +4
The forecasting of local GIC effects has largely relied on the forecasting of dB/dt as a proxy and, to date, little attention has been paid to directly forecasting the geoelectric…
Multipoint interplanetary coronal mass ejections observed with Solar Orbiter, BepiColombo, Parker Solar Probe, Wind and STEREO-A
C. Möstl, A. J. Weiss, M. A. Reiss +12
We report the result of the first search for multipoint in situ and imaging observations of interplanetary coronal mass ejections (ICMEs) starting with the first Solar Orbiter (Sol…
Meteorological factors and non-pharmaceutical interventions explain local differences in the spread of SARS-CoV-2 in Austria
Katharina Ledebur, Michaela Kaleta, Jiaying Chen +12
The drivers behind regional differences of SARS-CoV-2 spread on finer spatio-temporal scales are yet to be fully understood. Here we develop a data-driven modelling approach based…
Machine learning for predicting the Bz magnetic field component from upstream in situ observations of solar coronal mass ejections
Martin A. Reiss, Christian Möstl, Rachel L. Bailey +6
Predicting the Bz magnetic field embedded within ICMEs, also known as the Bz problem, is a key challenge in space weather forecasting. We study the hypothesis that upstream in situ…
Re-entrant phenomenon in diffuse ferroelectric, : Local structural insights and FORC study
Akash Surampalli, Ramon Egli, Deepak Prajapat +2
From the phase diagram as proposed by Lei et.al., [J. App. Phys 101, 084105 (2007)] a is chosen showing a diffuse phase transition between cubic to rhom…
The Observational Uncertainty of Coronal Hole Boundaries in Automated Detection Schemes
Martin A. Reiss, Karin Muglach, Christian Möstl +16
Coronal holes are the observational manifestation of the solar magnetic field open to the heliosphere and are of pivotal importance for our understanding of the origin and accelera…
Multi point analysis of coronal mass ejection flux ropes using combined data from Solar Orbiter, BepiColombo and Wind
A. J. Weiss, C. Moestl, E. E. Davies +15
The recent launch of Solar Orbiter and BepiColombo opened a brief window in which these two spacecraft were positioned in a constellation that allows for the detailed sampling of a…
Why are ELEvoHI CME arrival predictions different if based on STEREO-A or STEREO-B heliospheric imager observations?
Jürgen Hinterreiter, Tanja Amerstorfer, Martin A. Reiss +9
Accurate forecasting of the arrival time and arrival speed of coronal mass ejections (CMEs) is a unsolved problem in space weather research. In this study, a comparison of the pred…
Assimilation of the SCATSAR-SWI with SURFEX: Impact of local observation errors in Austria
J. Vural, S. Schneider, B. Bauer-Marschallinger +1
The proper determination of soil moisture on different scales is important for applications in a variety of fields. We aim to develop a high-level soil moisture product with high t…
In situ multi-spacecraft and remote imaging observations of the first CME detected by Solar Orbiter and BepiColombo
E. E. Davies, C. Möstl, M. J. Owens +20
On 2020 April 19 a coronal mass ejection (CME) was detected in situ by Solar Orbiter at a heliocentric distance of about 0.8 AU. The CME was later observed in situ on April 20th by…
