A study of the conditions necessary for the onset of mid-latitude spread F [PDF]

open access: yes
Ionospheric conditions associated with the initiation of spread F in the mid-latitude ionosphere were observed. The morphology of spread F at Puerto Rico was investigated.

Rocket studies of the lower ionosphere [PDF]

open access: yes
The earth's ionosphere in the altitude range of 50 to 200 km was investigated by rocket-borne sensors, supplemented by ground-based measurement. The rocket payloads included mass spectrometers, energetic particle detectors, Langmuir probes and radio ...

Speed-dependent collision effects on radar back-scattering from the ionosphere [PDF]

open access: yes
A computer code to accurately compute the fluctuation spectrum for linearly speed dependent collision frequencies was developed. The effect of ignoring the speed dependence on the estimates of ionospheric parameters was determined.
