Analysis and Interpretation of Total Electron Content Measurements

, 2005
TEC data from nearly 10 years of the TOPEX/Poseidon mission were analyzed to study the TEC climatology. First, the TEC data were binned by season, geomagnetic activity, and solar activity to create longitudinally averaged TEC maps in magnetic latitude and local time.

An EOF-Based Global Plasmaspheric Electron Content Model and Its Potential Role in Vertical-Slant TEC Conversion

Remote Sensing
Topside total electron content (TEC) data measured by COSMIC/FORMAT-3 during 2008 and 2016 were used to analyze and model the global plasmaspheric electron content (PEC) above 800 km with the help of the empirical orthogonal function (EOF) analysis ...

Estimating the Total Energy Content in Escaping Accelerated Solar Electron Beams

The Astrophysical Journal
Quantifying the energy content of accelerated electron beams during solar eruptive events is a key outstanding objective that must be constrained to refine particle acceleration models and understand the electron component of space weather.
