Ground based identification of dispersionless electron injections

Using data from an array of ground‐based single beam riometers and the CRRES Medium Energy B (MEB) particle detector we examine the signature of dispersionless electron injections. We find that it is possible to distinguish a dispersionless electron injection by it's integrated (>30 keV) flux signature at in situ satellites with a simple rise time criteria. If the total electron flux >30 keV exhibits a dramatic rise within 3 minutes then the …
