TL;DR: In this paper, the authors investigated the relationship between Jovian hectometric (HOM) and non-Io-related decametric (nonIoDAM) radio structure and showed that the cone half-angle of the emitting cone decreases as a function of frequency.
Abstract: [1] In this paper, we attempt to clarify the relationship between Jovian hectometric (HOM) and non-Io-related decametric (non-Io-DAM) radio structure. For that purpose, we extend the analysis by including more data and investigating statistical properties of the Jovian DAM and HOM radio emissions based on Cassini and Voyager observations, especially below 16 MHz. We have investigated these emissions observed by the Cassini, Voyager 1, and Voyager 2 spacecraft for specific Jovigraphic latitudes in the range of −3.7°–7.3° and local times in the range of 0.76–21.4 hours. We show a statistical comparison of Cassini, Voyager 1, and Voyager 2 data for occurrence probability in Central Meridian Longitude (CML) versus Io phase and in CML versus Frequency. The main results are as follows: (1) the detailed frequency structures of non-Io-related components can be seen for different spacecraft's local time and Jovigraphic latitude, (2) the high frequency of HOM extends up to near 10 MHz, and (3) a new DAM component, named the non-Io-D, appears from 40° to 60° CML in the frequency range of 7–11 MHz. On the basis of additional information of different behaviors of non-Io-B and non-Io-A structures in longitude depending on pre- and post-encounter of Cassini data, we improved the DAM angular beaming model that shows the cone half-angle of the emitting cone decreases as a function of frequency. We conclude that the changing beaming angle is not affected by Jovigraphic latitude of the spacecraft, but rather due to different local time of the source regions.

Journal ArticleDOI
TL;DR: In this article, the authors review the evidence for both systematic variations in the optical properties of the Io torus with magnetic longitude and for plasma corotational lag and conclude that there is no significant departure of the bulk plasma from corotation.

TL;DR: In this article, a seasonal pattern of the explained variance (r 2 ) by each of the variables has been found, at the beginning of the rainy season, the rainfall is correlated strongest with the longitude of the stations, during the main rainy season with the altitude and at the end of the rain seasons with the latitude of stations.
