Abstract

The paper discusses electric field and plasma density fluctuation measurements made on board the Porcupine II sounding rocket and on a free-flyer ejected from the main spacecraft. Simultaneous radar backscatter, dc electric field, and plasma density measurements are available. The results presented show electrostatic turbulence in the unstable auroral E region confined to a layer between 96 and 121 km. The similarities between the observations of two simultaneous payloads spaced a few kilometers apart indicate that on a large scale, the electrojet turbulence displays uniform characteristics. However, an investigation of the turbulence as a function of altitude reveals differentiation within the layer.
