THEMIS – A Canadian Perspective
1. A brief history of substorm work in Canada2. Canadian GeoSpace Monitoring3. A Canadian’s take on the THEMIS mission concept4. Coverage of the region where onsets occur5. Data from the ASI prototype6. A few thoughts on the data7. THEMIS-C tasks

From Atkinson, JGR, 1967.
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 CGSM2. THEMIS-C3. ICS-8

The ASI array provides a means of following CPS dynamics.
caveat
Information provided by this array is subjectto our understanding of the mapping and the relationship between CPS processes and theirauroral counterparts.

Our contributions – Implementation Phase
1. Deploy 16 GBOs2. Operate 16 GBOs3. Real-Time (RT) data retrieval from 16 GBOs4. Develop & maintain THEMIS-C website5. Develop scientific data products that are visually appealing6. Integrate RT data into summary & housekeeping web displays7. Maintain online archive of entire image data set8. Ensure flow through of UCLA magnetometer data9. Science (Substorms, Storms, Aurora, Machine Vision,….)
