Fig. 4

Scatter plot of vertical velocities calculated from Δh’Ft over HUA, versus those from the Doppler velocity of IS returns measured with the JIC radar. The points, shown as blue circles with white fill, were scaled and replotted from a figure in Rastogi et al. (1991). The red dots represent averages of Δh’Ft values that are clustered about a plotted V z F value. The label for zero velocity has a question mark because there may be points included that are not from the end of the PSSR. Inset: mean SSNs for years 1960 to 1980 (red), and 1990 to 2010 (green)
