Electron density at F1-layer heights in the last solar minimum (2007–2009)
We present the results of the analysis of annual variations in daily electron density (N) at heights 140–160 km for the last solar minimum (2007–2009) obtained from digisonde measurements at the ionospheric station Irkutsk (52° N, 104° E). New coefficients of the known semi-empirical model (SEM) des...
