1 THEMIS/GBO Engineering Peer Review 1 UCB, Oct. 17, 2003 Ground Based Observatories (GBO) Engineering Peer Review Oct. 17, 2003 THEMIS ASI Array – Canadian Role Eric Donovan on behalf of the NORSTAR Team University of Calgary & Athabasca University

2 THEMIS/GBO Engineering Peer Review 2 UCB, Oct. 17, 2003 CANOPUS ASI images (one minute cadence; 557 nm filter) for the late growth phase, early expansive phase of a substorm. The bottom panel is a keogram showing high resolution MSP data from the CANOPUS MSP, also located at Gillam. Note the spiral at 0332 UT, and well defined north-south structure at 0337 UT. Events such as this illustrate both the limitations and advantages of ground-based optical observations. The advantage is resolution (spatial here, and temporal not here, but easily obtainable). The disadvantage is limitation to spatial scales smaller than ALL relevant substorm phenomena.

20 THEMIS/GBO Engineering Peer Review 20 UCB, Oct. 17, 2003 Data Summary

21 THEMIS/GBO Engineering Peer Review 21 UCB, Oct. 17, 2003 Data Searching Machine Vision – Content Based Image Retrieval We are exploring automatic classification of images, rapid retrieval of images from large datasets, and determination of motion of auroral forms, all using sophisticated machine vision techniques. This classification and CBIR exercise reduces each image to a 48 element feature vector.

22 THEMIS/GBO Engineering Peer Review 22 UCB, Oct. 17, 2003 Optical Flow – a technique in which two-dimensional velocity distributions are obtained from image sequences [Partamies, Syrjäsuo, Janhunen (FMI), Hiebert]. Other techniques under development include… Tomography – sophisticated technique to infer heights from multiple overlapping fields of view [Jackel, Donovan, Partamies]. Energy Flux Determination – modification Janhunen [2001] method for THEMIS imagers to estimate energy flux [Partamies, Donovan, Janhunen (FMI)]. Data Analysis

23 THEMIS/GBO Engineering Peer Review 23 UCB, Oct. 17, 2003 Data Distribution Our contribution to distribution of THEMIS data will be carried out through the THEMIS webpage on NORSTAR-WEB. We will display real time data products as well as housekeeping information vital to keeping downtime to a minimum. All summary data, summary images, merged thumbnails, as well as tools for accessing the relational database will be publicly accessible. The “top 60’’ full time and space resolution image data base will be freely accessible to all THEMIS team members. The complete full time and space resolution image data base will be publicly accessible via temporary passwords that will be granted in response to specific data requests.
