Jayachandran, P.T., MacDougall, J.W., St-Maurice, J.-P., Moorcroft, D.R., Newell, P.T. and Prikryl, P. (2002). Coincidence of the ion precipitation boundary with the HF E region backscatter boundary in the dusk-midnight sector of the auroral oval. Geophysical Research Letters 29: doi: 10.1029/2001GL014184. issn: 0094-8276.

We have examined the location of the SuperDARN E region ionospheric backscatter boundary in the dusk-midnight sector and compared it with the equatorward boundary of the hard ion precipitation (b2i) determined from the DMSP satellite particle spectrograms in the dusk-midnight sector of the auroral oval. The locations of these two boundaries were found to be nearly coincident. This study evinces the capability of the SuperDARN radars to monitor the equatorward ion precipitation boundary (diffuse auroral boundary) and its dynamics irrespective of magnetic activity.
