Global Noise Plot

The plot below shows the noise level (median of the standard deviation of TEC time series across different constellations) across magnetic latitudes for the past eight weeks. For each magnetic latitude, the station with the least noise is selected. The planetary Kp and Ap indices are also plotted as indicators of geomagnetic activity and space weather conditions (see doi.org/10.5880/Kp.0001).
