Whistlers and Related Phenomenon Observed by e-POP-RRI

In this work, we present observations from the Radio Receiver Instrument (RRI) on the enhanced Polar Outflow Probe (e-POP, also known as SWARM-E). We have observed whistlers, proton whistlers, hiss and chorus. The observed polarization parameters, were used to determine the proton gyrofrequencies and cross-over frequencies. These parameters were compared against the modeled values from the IGRF model.
