Quasi-coherent chorus properties: 1. Implications for wave-particle interactions

Popis výsledku v původním jazyce

Chorus detected by Polar away from the magnetic equator generation region (similar to 25 degrees to 55 degrees magnetic latitude) was substantially different than chorus detected in previous studies within the similar to 0 degrees to 10 degrees generation region. (1) Two separate bands of chorus were often detected simultaneously: a higher-frequency downgoing (toward the Earth) band of waves and a lower-frequency upcoming band. (2) The downgoing waves are similar to 2 orders of magnitude more intense (similar to 10(-2) nT(2)) than simultaneously detected lower-frequency upcoming waves (similar to 10(-4) nT(2)). (3) Chorus, when viewed as a Fourier spectrum, appears as a band of semicoherent hiss. (4) A scenario and schematic is presented to explain these observations: chorus is presumed to be generated at the equator at large L*, propagate downward toward Earth and inward across L* shells, and then refract back up to the spacecraft location. (5) The waves detected at Polar latitudes di
