High bandwidth measurements of auroral Langmuir waves with multiple antennas

Chrystal Moser, James LaBelle, and Iver H. Cairns

Data sets

Data from the HIBAR 32600 sounding rocket mission S. Bounds https://phi.physics.uiowa.edu/science/tau/data0/rocket/HIBAR_36200/

Short summary

The HIBAR rocket launched on 28 January 2003 into the nightside aurora in order to measure high-frequency radio waves with both parallel and perpendicular antennae. The rocket encountered several short high-frequency radio wave bursts with a secondary wave associated with them, believed to be a product of a nonlinear wave–wave interaction of the initial wave with observed lower-frequency waves. Nonlinear waves are not often observed, and their dynamics are of significant interest.
