Lauren Blum - University of Colorado - GEM 2013 waves tutorial Summary Lots of different types of waves the main ones that might come up during the week in breakout sessions highlighted here (with a weighting towards radiation belts!) Relevance: waves can interact with particle populations in the magnetosphere acceleration and loss mechanisms for various particle populations (e.g. radiation belts, ring current) provide a way to transfer energy between different particle populations Lauren Blum - University of Colorado - GEM 2013 waves tutorial
