Pieternel F. Levelt,G. H. J. van den Oord,Marcel Dobber,A. Malkki,Hubregt J. Visser,Johan de Vries,Piet Stammes,J.O.V. Lundell,Heikki Saari +8 more
TL;DR: The Ozone Monitoring Instrument is a ultraviolet/visible nadir solar backscatter spectrometer, which provides nearly global coverage in one day with a spatial resolution of 13 km/spl times/24 km and will enable detection of air pollution on urban scale resolution.
Journal ArticleDOI

TL;DR: The Rosetta dual Langmuir probe instrument (LAP) as mentioned in this paper utilizes the multiple powers of a pair of spherical LAP probes for measurements of basic plasma parameters with the aim of providing detailed knowledge of the outgassing, ionization, and subsequent plasma processes around the Rosetta target comet.
Journal ArticleDOI
Subauroral electric fields observed by the Freja satellite: A statistical study
TL;DR: In this article, the authors scan Freja electric field data for subauroral electric fields (SAEF) to enable a comprehensive study of the ionospheric signatures of such electric fields.
Journal ArticleDOI
A statistical survey of auroral solitary waves and weak double layers 1. Occurrence and net voltage
TL;DR: In this article, the authors present an analysis using statistical methods of a large number of observations of weak double layers and solitary waves in auroral regions, made from Viking spacecraft, and show that these events are found in conjunction with beams of upward flowing ions.
Journal ArticleDOI
On theories attempting to explain observations of solitary waves and weak double layers in the auroral magnetosphere
TL;DR: In this paper, the theories concerning solitary waves and weak double layers in the auroral plasma are discussed and compared with Viking satellite observations and computer simulation experiment results of similar phenomena, and the lack of velocity vs amplitude relation in the Viking data is not consistent with the predictions of ion acoustic soliton theories and neither are the measured speeds of the structures.
