Planning for Observations of the Plasma Waves by Sounding Rockets in Antarctica

open access: yesAntarctic Record, 1975
The plasma wave observations in the polar ionosphere consist of two categories; the first is for the emission due to the particle precipitation and the second is for the emissions that are thought to be generated in the magnetosphere as a result of the ...
