Empirical Relationship Between LBH Auroral Emissions and Particle Precipitation

Observed auroral emissions are empirically correlated with observations of the precipitating electrons and ions that produce the emissions. The auroral emissions are observed with the SSUSI imager and the particle precipitation is observed by the SSJ/5 detector, both on the DMSP F16 satellite. Two months of continuous operations are processed and coincident observations of emissions and precipitation on the same field line assembled. The relationship between the precipitating energy flux of electrons and the intensity of LBHL emissions is fit to a power law. The relationship between the characteristic energy of precipitating electrons and the ratio of LBHS to LBHL emissions is also examined. While a relationship is clearly indicated, more data are needed to reduce the signal-to-noise ratio in the analysis results.
