...Using the DC magnetic field measurements from EMFISIS (Kletzing et al. 2013) with ECT particle fluxes we will achieve science closure by: (1) measuring the temporal evolution of phase space density gradients over a range of adiabatic invariants, (2) examining the evolution of the pitch angle distributions at different drift shells, (3) correlating with ULF field observations, and (4) looking for drift phase-bunching of electrons that resonate with ULF waves....
