4. THEMIS/GBO CDR Peer Review 4 Univ.of Calgary, Apr. 26-27, 2004 A Canadian Perspective A brief history of substorm work in Canada: 1.Current disruption & the substorm current wedge (Atkinson) 2.The phenomenology of the negative H bay, wedge, etc (Rostoker) 3.Substorm onset embedded deep within the CPS (Murphree, Elphinstone) 4.Substorm onset in an arc embedded in the bright proton aurora (Samson) 5.Role of ballooning in onset (Samson, Voronkov) 6.Global vs local stretching (Jayachandran, Donovan) 7.Possible role of ionospheric oxygen in the substorm (Cully) 8.Onset arc sometimes not pre-existing (Lyons, Voronkov) 9.Many many other contributions (graduate work, etc) The substorm is high priority problem in Canada: 1.One of five “grand-challenge” problems in CGSM 2.THEMIS-C 3.ICS-8

THEMIS/GBO CDR Peer Review 13 Univ.of Calgary, Apr. 26-27, 2004 The ASI array provides a means of following CPS dynamics. caveat Information provided by this array is subject to our understanding of the mapping and the relationship between CPS processes and their auroral counterparts.
