Fig. 3From: Method for modeling of the components of ionospheric parameter time variations and detection of anomalies in the ionosphereModeling results of the f o F2 data (Paratunka station, Kamchatka) for 21–25 February 1999 (LT): a observed (black line) and modeled f o F2 data by the f[2− 3 t] component model (blue line), b observed (black line) and modeled f o F2 data by the multicomponent model (MCM, blue line), c MCM errors, and d K-index for the Paratunka station. Graph c shows the standard deviations of the MCM errors (dashed lines)Back to article page
