D-region electron density and effective recombination coefficients during twilight – experimental data and modelling during solar proton events
Accurate measurements of electron density in the lower D-region (below 70 km altitude) are rarely made. This applies both with regard to measurements by ground-based facilities and by sounding rockets, and during both quiet conditions and conditions of energetic electron precipitation. Deep pene...
