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

  2. Overview • SATOPS overview • Satellite fix statistics 2008 • METSAT Conference Conclusions • Microwave Constellation • Quikscat • Improvements to Intensity Estimates

  3. SATOPS Mission • JTWC now has the sole Tropical Cyclone (TC) Reconnaissance Mission in USPACOM • 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

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

  5. 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

  6. 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 JAAWIN

  11. METSAT Conference Topics • Future of Satellites Improvements to operational intensity estimates • Participants • JTWC • NPOESS • NESDIS Satellite Analysis Branch • Naval Research Lab (NRL) • Fleet Numerical (FNMOC) • University of Wisconsin, CIMSS • NOAA-Science and Technology • Remote Sensing Systems • Lockheed Martin (Mark IVB) • SeaSpace (FMQ-17/TeraScan) • NWS Guam

  13. Future of Satellites-Conclusions • JTWC needs assistance in quantifying satellite platforms’ impact to operations • Ex: reduction in forecast errors, $ saved, sorties prevented • JTWC needs a systematic way to advocate for satellite programs (ex. GCOM scatterometer/AMSRE) • A temporal sampling requirement is needed for microwave imagery/sounders • Ex: imagery needed every 3 hours • Request increased resolution for MIS (NPOESS) sensor

  14. Quikscat • Essential to JTWC operations • Synoptic Analysis • Initial warnings often based on quikscat winds • Windsat/ASCAT- poorer spatial resolution • First scheduled replacement- Dual Frequency Scatterometer (DFS) 2016 • Potential to run second ASCAT 20 minutes after 1st • ASCAT flies on MetOp series Quikscat Windsat Ascat

  15. Dvorak Technique • Due to lack of aircraft recon, Dvorak primary tool for intensity estimates • Known weaknesses in Dvorak present problems for TDO/analyst • Few updates to process in 30 years • Subjectivity • Rapid intensification • Weakening systems • Weak, developing systems • Midgets/pinhole eye

  16. Improvements to Intensity Estimates • Need correct baseline intensity to improve intensity forecasting • Investigate use of CIMSS’ SATCON (Satellite Consensus) intensity estimate as a supplement to Dvorak • Weighted consensus of 3 automated satellite intensity estimates • ADT (Advanced Dvorak Technique) • AMSU (CIMSS) • AMSU (CIRA) • Collaborate to improve understanding of these intensity estimates • Priority for improvements concern storms less that 35 kts and rapid intensifiers
