ASPOC Data Products in the Cluster Active Archive

Torkar, K.; Jeszenszky, H.

The instrument ASPOC (Active Spacecraft Potential Control) controls the electric potential of the Cluster spacecraft by means of an ion beam. This modification of the charge balance improves the plasma measurements on board. Beneficial effects have also been observed for the electric field measurements by double probes (EFW). Comprehensive knowled…

Flexible Tools for Accessing the Cluster Archives

Roth, M.; De Keyser, J.; Gamby, E.

Nowadays, multi-spacecraft analysis is becoming common practice. The lack of homogeneity in data archive structure, access types and data formats results in a lot of time spent to search, retrieve and reformat data. We have developed a software model dealing with these issues. In this model, we integrate an abstraction layer for accessing and cach…

Cluster CAA Module for PaPCo

Goldstein, M. L.; Åsnes, A.; Friedel, R. +4 more

A PaPCo module for visualization of data from the CAA has been developed. This module retrieves data from the CAA web interface, and allows for discovery and plotting of new datasets. PaPCo is modular, open source IDL software that uses plug-in modules to bring new datasets on to a stack of time series plots (www.papco.org). PaPCo includes modules…

Plasma Flow Reversals in the Magnetotail and Their Implications on Substorm Models

Lui, A. T. Y.

Intervals of plasma flow reversals in the magnetotail are considered as times when the observing satellite encounters the process responsible for substorm disturbances. We consider the expected signatures during plasma flow reversals to evaluate the validity of two prevalent substorm models.
