  2. Overview • Inter-center Cooperative Support • NCEP backup (SPC, AWC & SEC back-up) • NAVAF - METSAT update • SPP Update • DMSP operational status • GOES-9 processing • POES Integration into World-Wide Merged Cloud Analysis (WWMCA) • METEOSAT Second Generation (MSG) • AFWA Initiatives • Operational DMSP data feed to UK Royal Navy • Space Weather Analysis and Forecasting (SWAFS) update • Mesoscale modeling: MM5 windows & improvements • WRF transition 2

  3. Inter-center Cooperative Support 3

  4. NCEP Backup • Storm Prediction Center • Backup on 27 Jan (fire alarm) & 11 Feb (comm outage) • Installed new workstations/applications interface on 28 Aug • Close collaboration continues • Aviation Weather Center • Backup on 31 Jul (software problems at AWC) • Completed upgrade to AFWA’s N-AWIPS Server on 12 Mar • Space Environmental Center • Requirements, key products, customers and needed redundant data/comm paths identified; warning S/W exchange in progress • Refining phased approach to backup • Congressional testimony provided 30 Oct 2003 • MM5 Backup for Eta Model • Four cycles daily, 45 km windows for North America and Alaska • Successful backup tests 25 Jul and 24 Oct 4

  5. NCEP Backup Cont. • Washington Volcanic Ash Advisory Center • Full W-VAAC backup operational at AFWA on 17 Jun 02 • Formal MOA in final stages of coordination • 4 backups in FY03 (25 Jan, 26 Mar, 3 Aug, 27 Aug) • “Washington VAAC would like to salute the responsive and collaborative effort the METSAT Applications Branch provided during these events.” • - Grace Swanson • Manager, W-VAAC 5

  6. NAVAF - METSAT • Delivery Performance • 99.8% of DMSP SIMPLE files delivered to FNMOC • Timeliness Performance • 94.1% of files delivered within 5 minute timeline Threshold • AFWA-to-FNMOC file transfers have slowed significantly since beginning of Sept • Working closely together to identify cause and fix action 6

  7. SPP Update 7

  8. DMSP Operational Status (28 Nov 03) FOUO/UCI OPR: NPOESS IPO/ADO FOUO/UCI 8

  9. GOES-9 Processing • GOES-9 Transition Complete • FOC 20 May 03 • Replaced Japanese GMS-5 • 28 full disks, 16 sectors/day • ~10X increase in data volume • over GMS-5 • May 03: Initiated FTW & simple file delivery to FNMOC • 8 Oct 03: Image Motion Compensation (IMC) switched off at request of Japanese. Fix to IMC off navigation errors implemented on all AFWA systems by 30 Oct 9

  10. POES Integration into WWMCA World-Wide Merged Cloud Analysis POES Implementation 1 Oct 03 Ingesting N-15, 16, 17 Benefit Global average pixel age reduced at least 10 minutes Tuning POES weighting factor will be adjusted as confidence in analysis increases Global, hourly cloud analysis. Provides input to National Intelligence Community, cloud forecast model, and global soil temperature and moisture analysis. 10

  11. 1 Oct 2003 03Z (Before POES) Average global pixel age: 66.34 minutes NH SH 2 Oct 2003 03Z (After POES) Average global pixel age: 47.75 minutes NH SH 11

  12. METEOSAT Second Generation (MSG) • AFWA to receive DOMSAT relay of MSG from Wallops • Will cost-share DOMSAT uplink expense with NASA • Awaiting EUMETSAT decision on NESDIS request for T1 data relay and sufficiency of proposed encryption scheme • Decision drives AFWA decryption/ingest architecture • Pressing forward with software work required to: • Use MSG channels to create a GOES-like capability • Exploit MSG capabilities for new applications • Awaiting Navy decision on preference for MSG delivery • SPP vs. DOMSAT • AFWA plans to switch from MET-7 to MSG Apr 04. 12

  13. MSG Benefits • Fifteen minute imaging cycle vs. current 30 min • More timely data for event detection/nowcasting • Twelve spectral channels vs. 3 on current MET series • More precise characterization of atmosphere • Increase horizontal resolution to 1km vs. current 2.5 km • Improved convective event detection capability • Improved platform reliability • Nominal on-orbit lifespan of 7 years vs. 5 years

  14. AFWA Initiatives 14

  15. UK Royal Navy Support • AFWA and UK Royal Navy‘s Fleet Weather and Oceanography Centre (FWOC) agree to exchange weather data • USAF/XOW approved DMSP data release 29 May 01 • Memorandum of Agreement (MOA) signed 23 Apr 03 • AFWA began sending FWOC all stored DMSP data in near real-time • for worldwide fleet support Apr 03 • Coordination underway for FWOC data feed to AFWA 15

  16. Auroral Boundary HF Illumination UHF Scintillation Particle Data SWAFS Spiral 1 Space Weather Analysis & Forecast System (SWAFS) • 33-month effort transferred space weather mission from 55th SWXS to HQ AFWA • Mainstreams space weather • Leverages AFWA production/dissemination system • Added Secret production capability • Products now available in Unclassified, Secret, and SCI environments 16

  17. Objectives for Spirals 2 & 3 New & improved capabilities using new data types and enhanced science-based algorithms/models (FY 03 - 07) -- Improve Ionospheric Analysis & Forecast Products -- Improve Auroral Specification Capabilities -- Support establishment of baseline AFWA-SEC backup capability -- Enhance product tailoring capability -- Increased classified processing -- Establish satellite analysis capability for anomaly assessment -- Model magnetosphere with real-time data assimilation -- Expand into solar wind forecasting -- Automate verification and model/product statistics 17

  18. Space Weather Models Update • Global Assimilation of Ionospheric Measurements (GAIM) Model • Operational capability FY06 • Replaces current climatology-based forecasting with state-of-the-art data assimilation system and physics-based forecasting capability • New space weather sensors on DMSP Block 5D-3 should improve our capabilities 18

  19. Mesoscale Modeling MM5 Operational Coverage • Driven by MAJCOM requirements • 17 Windows; 45 km; 72 hrs • 11 Windows; 15 km; 6-48 hrs • 2 Windows; 5 km; 6-24 hrs 19

  20. Mesoscale Modeling • Coupled Land Surface Model Implemented Spring 03 • Allows for atmospheric impact of changing soil temp/moisture • Assimilation of new data types • QuickScat, Feature Track Winds, ACARS • Polar Physics Enhancements Implemented • Better handling of strong inversions over snow cover • Theater-specific physics packages • 17 different tailored configurations presently in use • 3DVAR Enhancements • Theater-specific background error statistics provide more accurate initial conditions 20

  21. Mesoscale Modeling Cont. • Major FY03 IBM procurement resulted in 300% increase in available CPU cycles • -- Classified modeling capability is nearing IOC!! • AFWA-FNMOC submitted joint proposal to DoD High Performance Computing Modernization Office to establish Joint WRF Operational Testbed • Will install ~600 Gflops of processing capacity at each site • Project will demonstrate/prove viability of grid-computing technologies, validate WRF performance against DoD requirements, and support DoD-unique algorithm testing • Outlook is promising; expect final decision on funding within weeks 21

  22. Summary • Many successes during past year • Operationally backed up SPC, AWC and W-VAAC • Continuing overall excellent NAVAF METSAT performance • GOES-9 data replaced GMS-5, inserted POES in WWMCA • Working backup/cooperative support relationships with the NOAA SEC • Historic collaboration with Navy during Iraqi ground campaign • Strong collaboration continuing with NWS, Navy and research community on WRF • Busy Year...but we made a lot happen, thanks to great partnerships! 22
