Variability of background electron density (bNe) (a), Rate Of change Density (ROD) (b), Amplitude of Ne (c), filtered Ne in 10 s (d) and gradient Ne in 20 km scale (e) measured by Swarm A in the Northern (top) and Southern (bottom) hemispheres during the year with high (left) and low (right) solar activity levels. The red color shows the distribution in the low latitude region, green - in the mid-latitude, blue - in the high latitude and purple – in the polar region. Histograms for each parameter are presented on the same scale.
