Zusammenfassung:
Microbursts are impulsive injections of energetic (few keV to MeV) electrons into the atmosphere, primarily caused by nonlinear scattering by whistler mode chorus waves. While the relative importance of microburst precipitation as a loss process has not been fully quantified, many studies have shown microbursts may be a major loss source for outer radiation belt electrons. Conjunction observations between the FIREBIRD II CubeSats and Van Allen Probes (RBSP) from 2015 – 2019 have presented the opportunity to quantify the importance of microburst precipitation. We utilize this conjunction dataset, along with additional observations of chorus and microburst precipitation, when available, to constrain the size of the microburst-producing chorus region. We will present statistical results for the upper and lower bounds on the size of the region. Additionally, we will discuss wave properties, including amplitude, wave normal angle, duration, and microburst properties including flux and duration to further understand the observable dependence.
