Fig. 3From: Comparison of different methods to account for the plasmaspheric electron content in GNSS-derived ionospheric altimeter corrections and their impact on sea level trend estimationDifferences (diff) in ionospheric corrections (diono) with respect to smoothed dual-frequency correction for Jason-1 Cycle 015 (June 2002). Top plot shows the differences from the solution scaled with NeQuick ratio (3) in grey and the median for 5-degree latitude classes. The middle plot shows the median differences for all seven solutions and the bottom plot the respective standard deviation (std) per latitude classBack to article page
