    1. GOES-Based Multi-Platform Tropical Cyclone Surface Wind Product (MTC-SWA) John Knaff, Matthew Seybold June 25, 2008 10AM-1PM, WWB Room 607 Telecon: (877) 917-1654 5917706#

    2. GOES-Based Multi-Platform Tropical Cyclone Surface Wind Analysis CDR 2 June 25, 2008 *Preamble* This experimental product has been running for a couple of years at CIRA and being disseminated via the CIRA/RAMMB tropical cyclone web page. The product was recently funded by GOES-PSDI to move to operations in a two year period. However, there are new facets to this implementation Logistics The product was designed on LINUX based PCs that mirrored the capabilities at SAB. Product will need to be ported to IBM AIX64, which may cause some delays. Staffing Matthew Seybold is the new Tropical PAL replacing Ricky Irving

    5. GOES-Based Multi-Platform Tropical Cyclone Surface Wind Analysis CDR 5 June 25, 2008 Project Requirements and Goals Project Requirements SPSRB Requirement # 706-0011 from DOD/Joint Typhoon Warning to provide a tropical cyclone surface wind analysis from satellite sources at 6-hour interval for the analysis of 34-kt, 50-kt, 64-kt and maximum wind radii. Ingest Requirements Global Infrared imagery over tropical cyclones Global Cloud drift/ IR feature track winds Global QuikScat and if available A-Scat ocean wind vectors Global AMSU-based 2-d winds over tropical cyclones (NCEP operational product available via ftp)

    6. GOES-Based Multi-Platform Tropical Cyclone Surface Wind Analysis CDR 6 June 25, 2008 Project Requirements and Goals Processing Requirements (e.g., performance, validation, etc.) Timeliness While an analysis can be created 6-hourly, that analysis is still dependent on satellite data that can be 6-12 hours old. Accuracy of Product Accuracy of 5 ms-1 and precision of 1 ms-1 has already been demonstrated and documented (Knaff and DeMaria 2006) IR-winds provide proxy wind estimates within 200km of the TC center where other methods are least reliable. Validation using H*winds, which utilize aircraft reconnaissance will continue to be used for validation.

    7. GOES-Based Multi-Platform Tropical Cyclone Surface Wind Analysis CDR 7 June 25, 2008 Project Requirements and Goals Dissemination Requirement Automated Tropical Cyclone Forecast (ATCF) system formatted fixes for TPC, CPHC and JTWC Web pages for disseminating binary wind analysis data (archive of these) Web pages for displaying plots and textual information about currently active tropical cyclones.
