Difference of standard deviations per Jason-1 cycle between constant scaling and scaling by NeQuick ratio (top plot), constant scaling by different factors (middle), and between IRI-Plas and NeQuick scaling. The standard deviations are computed for different classes of geomagnetic latitude (low: red, high: blue, mid: grey). The grey line in April 2005 indicates the change from high solar activity to low solar activity (R12 = 30)
