  1. JTWC Satellite Operations(SATOPS) ATCF 15W SINLAKU Capt Kathryn Payne 27 April 2009

  2. Overview • Changes since last METSAT Conference • SATOPS Mission/Manning • Fixing Process/Stats • SATOPS Initiatives • Challenges

  3. TC Recon Network • Since the last METSAT Conference… • TC Recon Network disbanded • AFWA (KGWC) ceased fixing responsibilities (2007) • JTWC now has the sole Tropical Cyclone (TC) Reconnaissance Mission in USPACOM • AF Weather support for Mark IVB program suspended, restored

  4. SATOPS Mission Support JTWC TC Forecast Operations • METWATCH AOR for disturbances • Evaluate disturbances for TC genesis • Assess TC position/intensity • Synergistic relationship with Typhoon Duty Officers (TDOs) • Post-storm F-deck QC • Transition research to operations through collaboration

  5. Organizational Structure SATOPS: 1 AF Capt + 4 AF Enlisted + 2 AF civilians = 8 total

  6. SATOPS Tools • USAF / MARK IVB Satellite System • USN / FMQ-17 Satellite System • Automated Tropical Cyclone Forecast System (ATCF) • Geo-referenced • From FNMOC/NRL • FNMOC and NRL TC Web Pages

  7. Fixing Process • Position Fix every 3 hours • VIS, IR, Multi-spectral • Intensity Estimate every 6 hours • Dvorak Technique • Code and Transmit Bulletin • Process Other Agencies’ Fixes • Radar/Dropsonde fixes • Microwave Fixes as available • Now transmitted longline • Post-storm F-deck QC • Prior to final best track • After-the-fact fixes • Quality review of fixes • Feedback to analysts JAAWIN

  8. 2008 Satellite FixesBy Agency 9199 5% 16% 744 1951 96 6% 266 73% 69 51 29 126 45 5 Total Satellite Fixes = 12,581

  9. 2008 Geostationary Fixes By Platform (PGTW) 2% 36% 2504 62% 1462 77 27 Total Geostationary Fixes = 4,070

  10. 2008 Microwave Fixes By Platform (PGTW) 5% 15% 1716 34% 869 9% 644 17% 364 453 781 7% 284 13% Total Microwave Fixes = 5,111 Over half of PGTW fixes are now microwave

  11. 2004 vs. 2008 Fixes

  12. SATOPS Initiatives • AMSU Temperature Profiles • CIMSS and CIRA websites • Used to classify Subtropical Cyclones, transition of cold to warm core, assess ET, genesis?

  13. SATOPS Initiatives • DOTSTAR Dropsonde Data • Received via e-mail from Taiwan CWB • Data entered into ATCF • TDO gains valuable data for TC wind field • TC 15W (Sinlaku) • Based on DOTSTAR data, TDO increased • 35-kt wind radii by 40-45 nm • 50-kt wind radii by 25 nm • 64-kt wind radii by 20 nm

  14. SATOPS Initiatives • T-PARC 2008 • 3-hourly Dvorak fixes • Double Blind SATCON validation (CIMSS) • SATCON • CIMSS AMSU, CIRA AMSU, ADT • ADT/MW • Microwave Intensity Project • Follow on to work by Edson • Quikscat Ambiguities • Reinvigorating training process

  15. SATOPS Challenges • Changes to microwave constellation • NPOESS • Potential loss of Quikscat • Manning • Dvorak Technique • Developing Storms • Subtropical/Extratropical Storms

  16. SATOPS Contacts • OIC – Capt Kathryn Payne Capt Stephen Chesser (Aug 09) • NCOIC – TSgt Ken Viault MSgt Mike Oates (TBD) • E-Mail: firstname.lastname@navy.mil • Duty Satellite Analyst: • Commercial: (808) 471-3533 • DSN: (315) 471-3533 • SATOPS Office: • Commercial: (808) 474-3946 • DSN: (315) 474-3946
