    Benefits Enable timely use of GOES high resolution imagery data for algorithm development identification and tracking rapidly changing storm top features keys on overshooting tops (intense updrafts) from hi-res visible imagery incorporates info from GOES multi-spectral data (leverage from NASA) links satellite and radar products for thunderstorm tracking Multi-Line-Office, Multi-University Proposal, Leverages tasks from existing NOAA, NASA projects Builds on previous HPCC projects Makes use of high bandwidth data transfer Cost Effective means to further develop tools for research and operations Transfer output to operational NOAA units (AWIPS, N-AWIPS)? GOES Cloud top temperature: 11 June 08 2332 UTC ThunderTracker Version 3 Java server Updated for MySQL access Modified for CIRT requirements MySQL database for storm track info Larger image files – same format Flash client replaces Java applet More consistent layout No more memory issues – larger images, more tracks, etc. Better built-in charting capabilities The components System for Storm Analysis Using Multiple Data Sets FY 2007 Proposal to the NOAA HPCC Program Principal Investigator: Robert M. Rabin Collaborators: Valliappa Lakshmanan (CIMSS, University of Oklahoma)? Jaime Daniels (NOAA/NESDIS)? Arnie Gruber (NOAA/CREST, City College of New York)? Steven Weiss(NOAA/SPC)? Tom Whittaker (CIMSS, University of Wisconsin-Madison)? Proposal Theme: Technologies for Modeling, Analysis, or Visualization Funding Summary: FY 2007 $ 38,000 (in-kind matching: $15,000) OBJECTIVES Extend the web-based "Tool for storm analysis using multiple data sets" to include additional observational data and to provide short-term forecasts of storm location and relevant atmospheric conditions. Additional data will include derived products from the national network of WSR-88D Doppler radars not routinely available elsewhere: storm relative inflow and low-level air convergence hail diagnosis and rotation tracks Tracking of satellite, radar reflectivity fields and estimated precipitation will be linked together utilizing an existing approach which accounts for: movement of multiple scales movement of cloud and radar reflectivity and 'forecast' positions 1-2 hours into the future (Lakshamanan,2003)? Provide output from this tool to operational units in NOAA. This includes testing at the Storm Prediction Center (SPC), transfer of imagery to AWIPS and N-AWIPS, and input to a nowcasting system for greater New York City (in collaboration with NOAA cooperative institute CREST). Version 3 of ThunderTracker Version 1 was a simple display with animations and overlays Version 2 was a full-blown prototype that added many tracking features with some graph plotting Version 3 moves beyond those with A new, extensible database More complex graphing and overlays on client side Perhaps using Flash instead of Java on client side? A Web-based tool for monitoring MCS Storm Analysis Using Multiple Data Sets. Robert Rabin, Tom Whittaker 2004 Advances in Visual Computing, G. Bebis, R. Boyle, D. Koracin, B. Parvin, Ed(s)., Springer, 571-578. New Server-side Database MySQL based instead of previous “flat text file” Needed more flexibility to handle additional parameters and image types Tables fed from different sources but accessed through Java server-side technology Database Structure Two tables: Storm-connected data Each tracked storm has many items (columns)? Indexed by time; sorted on retrieval by storm-key number Images Table stores references to the image files, not the images Types: Satellite (visible, IR), Radar, Lightning Indexed by time MySQL chosen Easy, simple needs with no critical storage or retrieval considerations Use Flash instead of Java on Client Problems with Java (client) plug-in: Installation requires “admin privileges” Plug-in memory limit is only 64MB by default Hard to change default – different on each platform Incompatibilities with older Java versions If we move to Java 1.5 and Swing components, then old users of IE running Microsoft's Java will not work Flash advantages: No memory limit, easy install, alread on more than 95% of computers world-wide, easy and clean updates, excellent image and graphing libraries Use ActionScript for a “single-frame Flash movie” allows for animations, overlays, etc "K-means" technique for tracking satellite cloud top and radar reflectivity features.
