IMAGE RPI Monthly Electron Density Values

ResourceID
spase://NASA/NumericalData/IMAGE/RPI/PT1M

Description

The electron density values listed in this file are derived from the IMAGE Radio
Plasma Imager (B.W. Reinisch, PI) data using an automatic fitting program
written by Phillip Webb with manual correction.
The electron number densities were produced using an automated procedure (with
manual correction when necessary) which attempted to self-consistently fit an
enhancement in the IMAGE RPI Dynamic Spectra to either 1) the Upper Hybrid
Resonance band, 2) the Z-mode or 3) the continuum edge. The automatic algorithm
works by rules determined by comparison of the active and passive RPI data
[Benson et al., GRL, vol. 31, L20803, doi:10.1029/2004GL020847, 2004].
The manual data points are not from frequencies chosen freely by a human. Rather
the human specifies that the computer should search for a peak or continuum edge
in a certain frequency region. Thus even the manual points are determined, in
part, by the automatic algorithms. Of course that does not guarantee that the
data points are right, but it does eliminate some human bias.
