"Dependence of EMIC wave parameters during quiet, geomagnetic storm, and geomagnetic storm phase times." <i>Journal of Geophysical Research: Space Physics,</i> 121, no. 7 (2016) Wiley: 6277-6291. https://doi.org/10.1002/2016JA022694.https://hdl.handle.net/1911/97366As electromagnetic ion cyclotron (EMIC) waves may play an important role in radiation belt dynamics, there has been a push to better include them into global simulations. How to best include EMIC wave effects is still an open question. Recently many studies have attempted to parameterize EMIC waves and their characteristics by geomagnetic indices. However, this does not fully take into account important physics related to the phase of a geomagnetic storm. In this paper we first consider how EMIC wave occurrence varies with the phase of a geomagnetic storm and the SYM-H, AE, and Kp indices. We show that the storm phase plays an important role in the occurrence probability of EMIC waves. The occurrence rates for a given value of a geomagnetic index change based on the geomagnetic condition. In this study we also describe the typical plasma and wave parameters observed in L and magnetic local time for quiet, storm, and storm phase. These results are given in a tabular format in the supporting information so that more accurate statistics of EMIC wave parameters can be incorporated into modeling efforts.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
