Statistical Evidence for Contributions of Flares and Coronal Mass Ejections to Major Solar Energetic Particle Events [PDF]
, 2015 International audienceSolar energetic particle (SEP) events are related to flares and coronal mass ejections (CMEs). This work is a new investigation of statistical relationships between SEP peak intensities - deka-MeV protons and near-relativistic ...

Quantification of black carbon mixing state from traffic: implications for aerosol optical properties [PDF]
Atmospheric Chemistry and Physics, 2016 The climatic impacts of black carbon (BC) aerosol, an important absorber of solar radiation in the atmosphere, remain poorly constrained and are intimately related to its particle-scale physical and chemical properties.

The Observation of 10–50 KeV Solar Flare X-rays by the OGO Satellites and their Correlation with Solar Radio and Energetic Particle Emission [PDF]
Symposium - International Astronomical Union, 1968 More than 70 cases have been observed of energetic solar flare X-ray bursts by large ionization chambers on the OGO satellites in space. The ionization chambers have an energy range between 10 and 50 KeV for X-rays and are also sensitive to solar protons and electrons.

On realistic size equivalence and shape of spheroidal Saharan mineral dust particles applied in solar and thermal radiative transfer calculations [PDF]
Atmospheric Chemistry and Physics, 2011 Realistic size equivalence and shape of Saharan mineral dust particles are derived from in-situ particle, lidar and sun photometer measurements during SAMUM-1 in Morocco (19 May 2006), dealing with measured size- and altitude-resolved axis ratio ...

Advanced Engineering Materials, EarlyView.A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.

Small scale energy release driven by supergranular flows on the quiet Sun [PDF]
, 2007 In this article we present data and modelling for the quiet Sun that strongly suggest a ubiquitous small-scale atmospheric heating mechanism that is driven solely by converging supergranular flows. A possible energy source for such events is the power

Solar Energetic Particle Events with Extremely High 3He Content Observed by Solar Orbiter
The Astrophysical JournalWe performed a survey of ^3 He-rich events using observations from the Suprathermal Ion Spectrograph on the Solar Orbiter mission from 2020 to 2024. We identified 57 ^3 He-rich events, each showing clear ^3 He enhancements above the background and ^3 He/
