The Evolution of Chorus Emissions Over Time and Magnetic Latitude

Chorus wave emissions are pervasive electromagnetic waves observed throughout the inner magnetosphere, and can intensify significantly during enhanced geomagnetic activity. Chorus waves have been shown to drive a particular type of precipitation that is composed of ring current and radiation belt losses and results in the quasi-periodic optical ionospheric phenomenon called pulsating aurora. Understanding how chorus waves evolve over time following periods of generation and rapid growth (i.e. injection-driven) and how they evolve as they propagate from equatorial sources to higher magnetic latitudes will lead to insights about how they drive energetic electron precipitation.
