Modeling results of the f _o F2 time series components (Paratunka station, Kamchatka) for 4–17 February 2011 (UT): a observed (black line) and median of the f _o F2 time series (gray line), b actual (black line) and modeled f[2^− 3 t] component values (blue line), c actual (black line) and modeled g[2^− 3 t] component values (blue line), d errors of the f[2^− 3 t] component model, e errors of the g[2^− 3 t] component model, f International Reference Ionosphere (IRI) model errors, and g K-index for the Paratunka station. Graphs d and e show the standard deviations of the component model errors (dashed lines)
