Planetary Waves in the Ionosphere

1998
Abstract : The objectives of this grant are to delineate and to better understand oscillations in ionospheric structure which occur at planetary-wave periods (i.e., 2-10 days). Effort has concentrated on analyses of about 30 years' of archived ionosonde data from a global array of stations, and some satellite-based measurements of total electron ...

Beaming of electromagnetic radiation by planetary ionospheres

Icarus, 1970
Abstract Use is made of elementary analytical and experimental results to predict an increased directivity from sources radiating inside or outside plasma layers. It is found that the directivity enhancement is higher when the source is between two plasma layers.

Dications in the planetary ionospheres

2006
The planetary ionosphere models usually consider singly charged ions only and neglect doubly charged ions and especially the molecular ones since they were thought to be unstable in ionospheric conditions. Generally speaking, doubly charged ions are difficult to detect by mass spectrometry because their q/m number is the same as other more abundant ...

Planetary Ionospheric Disturbance Inspired Optimization Algorithm

The planetary ionosphere is a region of the planetary atmosphere ionized by solar radiation and high-energy particles, and its electron density exhibits dynamic fluctuations. Ionospheric disturbances are characterized by rapid local response, wave propagation, random external perturbations, and recovery mechanisms. Drawing on the physical mechanisms of
