Empirical model of Poynting flux derived from FAST data and a cusp signature

Abstract: [1] Empirical models of the Poynting flux and particle kinetic energy flux, associated with auroral processes, have been constructed using data from the FAST satellite and are available online. The models output flux maps as a function of several geophysical parameters: (1) clock angle of the interplanetary magnetic field (IMF), (2) magnitude of the IMF in the GSM y-z plane, (3) solar wind speed, (4) solar wind number density, (5) magnetic dipole tilt angle, and (6) the AL index (optional for Poynting flux).

“…In general, observations of Poynting flux, Joule heat, and other forms of energetic response are averaged to yield an empirical result. As pointed out by Cosgrove et al (2014), this results in a ''smearing'' of the data. This kind of analysis brings out large-scale, steady-state phenomena but it does not represent well highly dynamic events like magnetic storms.…”

“…The widely accepted paradigm is documented in papers by Weimer (2005), Cosgrove et al (2014), McHarg et al (2005, and others, in which the auroral zones and cusp dominate highlatitude energy input. The main reason for the discrepancy between our results and previous work lies in the way the data have been treated.…”

“…Alternatively, high correlations demonstrate a relationship exists but do not necessarily provide information about causation. EOFs are not necessarily organized according to physical cause. They capture the direction of most variability in the data subject to the constraint that it is orthogonal to each previous, more prominent, direction of variability, and irrespective of the correlation with physical drivers [ Cosgrove et al , ].…”

“…Knipp et al () report extremely enhanced energy deposition, sometimes locally reaching 170 mW/m 2 , associated with strong IMF B y conditions. Cosgrove et al () introduce a comprehensive empirical Poynting flux model as a function of several IMF and solar wind parameters. All of these studies deal with total Poynting flux.…”
