Dayside auroral dynamics: South Pole - AMPTE/CCE observations

Ground-based observations of the auroral zone and polar cap ionospheric responses to dayside transient reconnection

Observations from the EISCAT VHF incoherent scatter radar system in northern Norway, during a run of the common programme CP-4, reveal a series of polewardpropagating F-region electron density enhancements in the pre-noon sector on 23 November 1999. These plasma density features, which are observed under conditions of a strongly southward interplanetary magnetic field, exhibit a recurrence rate...

The dynamics and relationships of precipitation, temperature and convection boundaries in the dayside auroral ionosphere

A continuous band of high ion temperature, which persisted for about 8 h and zigzagged north-south across more than five degrees in latitude in the dayside (07:00– 15:00 MLT) auroral ionosphere, was observed by the EISCAT VHF radar on 23 November 1999. Latitudinal gradients in the temperature of the F-region electron and ion gases (Te and Ti , respectively) have been compared with concurrent ob...

Millimeter and Submillimeter Observations from the South Pole

During the past decade, a year-round observatory has been established at the geographic South Pole by the Center for Astrophysical Research in Antarctica (CARA). CARA has fielded several millimeterand submillimeter-wave instruments: AST/RO (the Antarctic Submillimeter Telescope and Remote Observatory, a 1.7-m telescope outfitted with a variety of receivers at frequencies from 230 GHz to 810 GHz...

High Resolution Radar Polarimetric Observations of the Lunar South Pole

Introduction: NASA's exploration plans for the Moon are being driven at least in part by the possibility that there may be exploitable deposits of water ice at the lunar south pole. Whether the elevated hydrogen abundance measured by Lunar Prospector corresponds to water ice and, if so, in what form is still a matter of conjecture. Bi-static radar observations with the Clementine orbiter are pu...
