Abstract:

The AFRL algorithm obtains equatorward boundaries of auroral precipitation from electron fluxes measured by SSJ sensors on DMSP satellites. Gussenhoven and coworkers provided the empirical basis for the algorithm, showing that auroral boundaries correlate linearly with the Kp geomagnetic index. This report describes a the DMSP database, b derived statistical parameters, c tests performed on these statistics, and d the utility of test results. We illustrate the algorithms method of operation through four detailed boundary identifications obtained during a full orbit of DMSP satellite F16 on 25 July 2004.
