Description
Recent results show that the solar wind helium abundance and normalized cross helicity can be used to classify solar wind from continuously and intermittently open source regions. In the associated parameter space, ICMEs appear where the helium abundance is enhanced and the cross helicity is low. This region of the plane also has an enhanced solar wind compressibility. Using 30 years of Wind Faraday cup date, we demonstrate the ICMEs can be identified using these three quantities. This work stands in contrast and is complementary to recent efforts that use large scale magnetic field observations and machine learning algorithms.
