...On the dayside, Baker et al. (1997) and Pinnock and Rodger (2001) used SuperDARN observations to estimate the dayside reconnection voltage, employing the spectral width boundary as an estimate of the location of the OCB....

...The boundaries of the auroral oval can be determined locally by ground-based observations such as radars (Pinnock and Rodger, 2000; Moen et al., 2004; Aikio et al., 2006) or low-altitude satellite observations (Newell et al., 1996; Wang et al., 2005), while optical imagers from high-altitude…...

...Pinnock and Rodger (2001) excluded all backscatter with spectral widths less than 150 m/s from a composite of scans from 4 SuperDARN radars and then smoothed the remaining equatorward backscatter boundary to obtain their estimate of the boundary....

...It should be stressed that we are not proposing that the technique for deriving the time-of-¯ight of cusp ions be used to infer properties of the reconnection X-line on the magnetopause, which can be done with greater accuracy using satellite particle data (e.g. Lockwood et al., 1995)....
