Coronal Mass Ejections are a spectacular an violent phenomenon of the solar atmosphere
with repercussions throughout the entire heliosphere. They are a spectacular
sight when seen to erupt from the Sun with the aid of a coronagraph such as LASCO
on the Solar and Heliospheric Observatory SoHO. They are a violent phenomenon
when arriving at Earth, pounding on our magnetosphere, and sometimes disrupting
all kinds of achievements of the industrial and information age.
The concept of summerschools and workshops at the Kanzelho¨he Solar
Observatory, Ka¨rnten, Austria, devoted to up-to-date topics in solar physics
has been proven to be extremely successful, and thus in August/September
2003 the third combined summerschool and workshop was held there.
This book contains the proceedings of the Summerschool and Workshop
“Solar Magnetic Phenomena” held from 25 August to 5 September
2003 at the Solar Observatory Kanzelho¨he, which belongs to the Institute
for Geophysics, Astrophysics and Meteorology of the University of Graz,
Breaking waves on the sea cause the ejection of many tiny droplets of seawater into the atmosphere.
These droplets dry by evaporation leaving sea salt particles suspended in the air. Particles are also directly
emitted by the bursting of air bubbles on sea surface Such particles are generally in the size range between
1 to 20µm. . Whilst these particles are, in the main, rather coarse in size, a minor part of their mass is
in particles small enough to have an appreciable atmospheric lifetime, which has been estimated as three
