Approximation of Daily AMS‐02 Spectra With Machine Learning Methods
Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.Abstract Almost three thousand daily AMS‐02 proton spectra from 2011 to 2019 offer the most precise and extensive data set of cosmic ray spectra covering a wide energy range. As such, they offer a unique opportunity to test machine learning algorithms for approximating cosmic ray proton spectra based on the inputs usually available to solar modulation ...

CNN‐Based Model for 3D CME Parameter Prediction – A Proof of Concept
Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.Abstract Accurate 3D reconstruction of coronal mass ejections (CMEs) is essential for understanding their propagation and improving space weather forecasts. In this study, we present a proof‐of‐concept deep learning framework that predicts seven parameters from synthetic multi‐view coronagraph images.

Heliospheric consequences of solar activity in geophysical and interplanetary phenomena
Geofísica Internacional, 2004 We have done an analysis of the total solar magnetic flux, polar coronal hole area and sunspots. We investigate their long term evolution over several solar cycles and their possible relationship with interplanetary shocks, sudden storm commencements at ...

Solar-Heliospheric Physics [PDF]
Proceedings of 35th International Cosmic Ray Conference — PoS(ICRC2017), 2017 This rapporteur paper summarizes the 99 presentations on solar-heliospheric physics at the 35th International Cosmic Ray Conference. These spanned a dizzying array of physical phenomena, especially time-dependent phenomena associated with solar storms, the 27-day solar rotation, the $\sim$11-year sunspot cycle, and the $\sim$22-year solar magnetic ...

MHD Forecasting of Solar Wind With Coronal Mass Ejections
Space Weather, Volume 23, Issue 12, December 2025.Abstract We present a model, implemented as an online service, for predicting the speed and density of solar wind in the inner heliosphere and near Earth. The model is based on a numerical magnetohydrodynamics code PLUTO. The inner boundary maps are continuously obtained from the National Centers for Environmental Prediction, where they are updated 1 ...
