Abstract
This paper uses energy flux data from the DMSP F6 thru F19 satellites to construct a new equatorward auroral boundary model. This method of processing the data allows one to easily extend boundary detections to different instrument generations because it is based on a standard deviation value instead of hard thresholds. Using this method, the paper provides statistics from just under 1 million auroral boundaries between 1986 and 2014. These statistics are based on normal distribution fits for each Kp/Hp and MLT bin, which allows one to specify the boundary for an arbitrary distribution percentile. The paper compares how the model performs for driving by Hp30, Hp60, and Kp and finds that Hp30 is the best representation of the data. Finally, the paper provides specifications to recreate the model for the 50th and 95th percentiles for Kp and Hp30.
