Influence of FACs and equatorward ion and electron precipitation boundary separation on SAPS.
SAPS occurrence statistics paper
Expand the existing database of SAPS events (to 2014)
Resubmit the paper with the new (expanded) set of SAPS events.
Statistical model of SAPS velocities
Apply L-shell fitting to l-o-s velocities for all events in the SAPS database.
Obtain statistical variations in SAPS velocities with Dst. (or may be other indicators - IMF?)
Compare observations with previous studies
Develop a statistical model of SAPS velocities and potential contours.
Given a Dst index (or other geomagnetic activity indicator) value, generate estimate of SAPS velocities, potentials - how does it compare with theoretical models?
SD - VAP conjugate observations
Develop a database of conjugate SD - VAP SAPS observations.
First statistical study showing direct comparison of observations in magnetosphere and ionosphere ?
How do SD observations of SAPS electric fields compare with the DC electric fields in VAP?
Do the amplitudes and variations in electric fields compare well?
What are the influencing factors - Dst, ionospheric conductivity, magnetic mapping ?
Influence of R2 FACs and boundary separation on SAPS
From 2015, we can derive ion and electron precipitation boundaries from POES satellite data.
AMPERE provides R2 FAC data.
R2 FACs should be equatorward of SAPS. Is this the case even for quiet time SAPS? Does this apply only at certain MLTs?
Does boundary separation happen at all MLTs and all geomagnetic conditions?
