CLU2 STAFF-SA Caveats - Power Spectral Density negative values

This dataset contains caveats for the SM datasets from the STAFF-SA instrument on Cluster 2 spacecraft. For a given time and frequency are given the PSD negative values that have been replaced in the PSD data product by a fillvalue.

Cluster 2 RAPID Prime Parameters

This data set contains the Cluster 2 RAPID Prime Parameters (spin averaged) : omni-directional particle fluxes in two energy ranges for 4 species, plus field-aligned anisotropies for protons and electrons. Caveats The calibration data applied are the most reasonable for a quick and standardised calculation of the particle fluxes. They do not attempt to include cross-calibrations among the spacecraft, since these are extremely complicated, requiring case-by-case analysis. Thus the same geometry factors are applied to...

Cluster 1 WHISPER Prime Parameters

This data set contains the Cluster 1 WHISPER Prime Parameters : the electron density and plasma wave spectral density integrated over the frequency range, plus the status of operations.
