  8. NOAA’s FY 2011 Budget

  9. Deep Space Climate Observatory (DSCOVR) Solar Wind Mission • The DSCOVR spacecraft will be refurbished and readied for launch in December 2013 • Satellite and sensors will be transferred to NOAA • Refurbishment of satellite and Plas-Mag sensor will be performed at NASA/GSFC under reimbursement by NOAA • USAF plans to begin acquiring a launch vehicle in 2012 • All data will be downlinked to the Real Time Solar Wind Network (RTSWnet) • DSCOVR Earth science sensors are in the process of being refurbished • A commercial partner will be solicited for the mission to help evaluate the potential of commercial service for a follow-on mission

  10. Compact Coronagraph (CCOR) • NOAA and the Naval Research Laboratory are currently collaborating on a Phase A study for a demonstration compact coronagraph • A reimbursable project for sensor development will begin at NRL in FY11 • CCOR is a reduced mass, volume, and cost coronagraph design • 6 kg telescope, 17 kg for sensor • Optical train is 1/3 the length of traditional coronagraph designs • CCOR will fly on DSCOVR if schedule permits • CCOR has been submitted to the DoD Space Test Program (STP) for flight as a back-up strategy if necessitated by schedule

  11. COSMIC Follow On (COSMIC 2) • COSMIC begins to degrade in 2011 (end of life) • Significant data reduction expected by 2014-2015 due to loss of satellites • President’s budget supports initial launch of COSMIC 2 in 2014 • Proposed partnership with Taiwan – • Taiwan to provide: 12 spacecraft and integration of payloads onto spacecraft, ground system command & control • NOAA to provide: 12 payloads (receivers), 2 launches, ground system data processing • System will provide 8000+ worldwide atmospheric and 10-12,000 ionospheric soundings per day (all weather, uniform coverage over oceans and land) • Commercial data purchase for enhancement/gap coverage under consideration

  16. Solar Ultra-Violet Imager (SUVI) • Completely Different than GOES NOP: • GOES NOP SXI observes in x-rays (0.6-6 nm) • SUVI will observe in the Extreme Ultra-Violet (EUV) (10-30 nm) • Narrow band EUV imaging: Permits better discrimination between features of different temperatures • 30.4 nm band adds capability to detect filaments and their eruptions • 6 wavelengths (9.4, 13.1, 17.1, 19.5, 28.4, and 30.4 nm) 2 minute refresh for full dynamic range • SUVI will provide • Flare location information (Forecasting event arrival time and geo-effectiveness) • Active region complexity (Flare forecasting) • Coronal hole specification (High speed solar wind forecasting) • SOHO EIT images currently used as a proxy for SUVI data: • comparable resolution • slower cadence • incomplete spectral coverage • SDO AIA provides improved proxy data: • 16X as many pixels as SUVI • Higher cadence • image in 8 EUV bands, 5 of which match SUVI exactly SDO AIA 30.4 nm

  21. Space Weather in the World Meteorological Organization (WMO) Motivation for WMO: • Space Weather impacts the Global Observing System and the WMO Information System • Space Weather affects important economic activities (aviation, satellites, electric power, navigation, etc.) • Synergy is possible with current WMO meteorological services and users, such as sharing observing platforms and issuing multi-hazard warnings • Several WMO Members have Space Weather with Hydro-Met Agency • Effective partnership with International Space Environment Service THE POTENTIAL ROLE OF WMO IN SPACE WEATHER A REPORT ON THE POTENTIAL SCOPE, COST AND BENEFIT OF A WMO ACTIVITY IN SUPPORT OF INTERNATIONAL COORDINATION OF SPACE WEATHER SERVICES, PREPARED FOR THE SIXTIETH EXECUTIVE COUNCIL April 2008

  22.

  23. Summary • • Space weather research and forecasting require coordinated observations from around the globe • • ACE follow-on (DSCOVR) is moving forward. Coronagraph is uncertain on DSCOVR. Globally distributed antennas, with backups, are required. • • Upgraded geosynchronous measurements will soon be available, some LEO capabilities will be lost, next-generation radio-occultation is anticipated. • • International partnerships are increasingly important, and progress is being made.
