Effect of Shock Normal Orientation Fluctuations on Field-Aligned Beam Distributions
Lucek, E. A.; Mazelle, C.; Wilber, M. +5 more
We address the unsolved question of how foreshock field-aligned beam (FAB) parallel temperatures are produced. Studies including numerical simulations and recent observations have indicated that shocks can be nonstationary and include embedded spatial structures with varied scales. As a first step towards assessing the impact of such variability o…
EDI Data Products in the Cluster Active Archive
Quinn, J.; Paschmann, G.; Vaith, H. +4 more
The Electron Drift Instrument (EDI) contribution to the Cluster Active Archive (CAA) is described. Presented are descriptions of the EDI instrument, the various CAA/EDI data products, the CAA ingestion schedule and the current EDI status. An example of a science application is given for one of the main EDI data products available in the CAA.
Electron Density Estimation in the Magnetotail: a Multi-Instrument Approach
Escoubet, C. P.; Fazakerley, A. N.; Santolík, O. +7 more
Electron density is a key physical quantity to characterize any plasma medium. Its measurement is thus essential to understand the physical processes occurring in the environment of a magnetized planet, both macroscopic and microscopic. Since 2000, the four satellites of the European Space Agency (ESA) Cluster mission have been orbiting the Earth …
ESOC Data Products in the CAA
Volpp, J.; Sieg, D.
This document intends to help users to find information provided by the Cluster Flight Control and Flight Dynamics teams. Both teams deliver to the Cluster Active Archive a wide range of operations related information, which could be helpful as background information for science data processing. The products range from high level summary reports t…
Energetic Particles in the Cusp: A Cluster/RAPID View
Asikainen, T.
Energetic particles have been persistently observed in the exterior cusp by different satellite missions such as POLAR, Cluster-II, Viking, ISEE etc. Yet the source and the acceleration mechanism of these particles have remained unclear. In this paper I review our studies of energetic particles in the cusp and the nearby high-latitude region of cl…
Digital Wave Processor Products in the Cluster Active Archive
Alleyne, H. St. C.; Walker, S. N.; Yearby, K. H. +4 more
The Digital Wave Processor (DWP) is the central control and data processing instrument for the Cluster Wave Experiment Consortium. DWP products in the Cluster Active Archive (CAA) provide a mainly supporting function for the rest of the consortium. This includes a time correction dataset which allows the standard timing accuracy of 2 ms to be impr…
Evolution and Energization of Energetic Electrons in the Inner Magnetosphere
Fennell, J. F.; Roeder, J. L.
In this paper we present a review of what we know about the evolution and energization of energetic electrons in the inner magnetosphere. We emphasize what we have learned since the review by Friedel et al. [17] that discussed in detail the possible acceleration mechanisms for these electrons. The primary result has been a greater focus on local a…
Double Star: Mission, Instruments and Joint Observations
Escoubet, C. P.; Fazakerley, A. N.; Dunlop, M. W. +5 more
The Chinese National Space Agency (CNSA) Double Star (DSP) spacecraft, TC-1 and TC-2 were launched in December 2003 and July 2004 into near equatorial and polar orbits respectively. During more than 3 years of operations they have maintained a close phasing with the ESA four-spacecraft mission to produce the first, well coordinated multi-scale mea…
Cluster Wideband Data Products in the Cluster Active Archive
Pickett, J. S.; Santolík, O.; Christopher, I. W. +2 more
Cluster Wideband Data (WBD) plasma wave receivers are mounted on all four of the Cluster spacecraft providing approximately 4-7% orbit coverage since mission operations began in February 2001. Data obtained by the WBD instruments are downlinked in real time to various Deep Space Network (DSN) and Panska Ves (PV) ground stations. The strengths of t…
Acceleration of >40 keV Electrons in Near-Earth Magnetotail Reconnection Events
Taylor, M. G. G. T.; Åsnes, A.; Borg, A. L.
Reconnection of magnetic field lines have been invoked as an acceleration mechanism producing significant amounts of super-thermal electrons in the high energy range. However, in a recent paper by Åsnes et al., 2008, energetic particle generation during geomagnetic active times was shown to be mainly caused by plasma sheet heating rather than reco…
