  1. Space Weather Measurements: Capabilities and Needs Howard J. Singer NOAA Space Environment Center NSF Workshop on Small Satellite Missions for Space Weather and Atmospheric Research George Mason University, Arlington, VA May 17, 2007

  2. Outline Space Weather Satellite Observing Capabilities in Operations Space Weather Observing Needs NOAA’s Observing System Architecture Conclusions Acknowledgments: Baker, Doggett, Murtagh, O’Connor, Onsager, Tayler, Viereck Space Weather Measurements: Capabilities and Needs

  3. Monitor, Measure and Specify:Data for Today’s Space Weather • Ground Sites • Magnetometers (NOAA/USGS) • Thule Riometer and Neutron monitor (USAF) • SOON Sites (USAF) • RSTN (USAF) • Telescopes and Magnetographs • Ionosondes (AF, ISES, …) • GPS (CORS) • SOHO (ESA/NASA) • Solar EUV Images • Solar Corona (CMEs) ESA/NASASOHO • ACE (NASA) • Solar wind speed, density, temperature and energetic particles • Vector Magnetic field L1 NASAACE NOAA GOES NOAA POES • GOES (NOAA) • Energetic Particles • Magnetic Field • Solar X-ray Flux • Solar EUV Flux • Solar X-Ray Images • POES (NOAA) • High Energy Particles • Total Energy Deposition • Solar UV Flux Space Weather Measurements: Capabilities and Needs

  4. Utilizing Non-NOAA Observations and Data • By continued awareness of, and involvement in research programs, SEC can encourage and work together with non-NOAA satellite programs to provide data for operational use. • ACE: Through an interagency partnership, NASA modified the ACE spacecraft to provide continuous real-time data • IMAGE: Through an interagency partnership, NASA modified the IMAGE spacecraft to provide continuous real-time data. • Living With A Star: Through involvement on NASA definition panels, SEC has encouraged NASA to define satellite programs that include utility to space weather forecasting and specification (Solar Dynamics Observatory, RBSP, …) • STEREO:Through interagency planning, NOAA is obtaining real-time data from a satellite beacon that is being used by operations for forecasts and warnings of impending geomagnetic storms.

  5. Uses of Space Weather Data Estimated Planetary K index Based on Ground Magnetometers • Indicators of State of the System • Input to Drive Models • Data Assimilation • Validate Model Output • Instrument Calibration/Validation • Research Magnetospheric Specification Model Input parameters: Kp, Dst, Vpc, PC pattern, equatorward boundary auroral precipitation, solar wind velocity and density, IMF, DMSP precip flux, sum Kp Space Weather Measurements: Capabilities and Needs

  6. Uses of Space Weather Data:Magnetometer Data Needed for Space Weather Model Validation The geosynchronous magnetic field is used to validate models and eventually may be assimilated into models. It will be vital for models run in operations. CISM: Huang et al. U. Mich. Gombosi et al. U. Of Michigan (Gombosi et al.) Multiple groups of MHD modelers rely on the GOES magnetic field data for validating their models. UNH: Raeder et al. Space Weather Measurements: Capabilities and Needs

  7. Major Space Weather Customer Needs • Communication outage probability • Solar energetic particle probability • Flare probability • Ground dB/dt probability • Human radiation exposure probability • Satellite radiation exposure probability • Ionospheric Total Electron Content probability Space Weather Measurements: Capabilities and Needs

  8. NOAA Space Environment CenterHighest Priority Operational Needs • Solar energetic particle event forecasts, including start time, end time, peak flux, time of peak flux, spectra, fluence, and probability of occurrence • Solar wind data from L1 • Solar coronagraph data • Energetic electron flux prediction for International Space Station • Regional geomagnetic activity nowcasts and forecasts • Ionospheric maps of TEC and scintillation (real-time and future) • Geomagnetic indices (e.g., Ap, Kp, Dst) and probability forecasts • Solar particle degradation of polar HF radio propagation • Background solar wind prediction 2006; not priority ordered Space Weather Measurements: Capabilities and Needs

  9. NOAA Space Environment CenterHigh Priority Operational Needs • Geomagnetic activity predictions (1-7 days) based on CME observations, coronal hole observations, solar magnetic observations, and ACE/EPAM observations • Visualization of disturbances in interplanetary space (e.g. view from above the ecliptic tracking an ICME) • Geomagnetic storm end-time forecast • Real-time estimates of geomagnetic indices • Real-time quality diagnostics (verification) of all warning/watch/forecast products • Routine statistical and/or numerical guidance for all forecast quantities (e.g., climatological forecasts of flares, geomagnetic indices and probabilities, and F10.7—similar to NWS Model Output Statistics) • Improved image analysis capability (e.g., for GOES-13 SXI, STEREO, SDO) • Short-term (days) F10.7 forecasts • Short-term (days) X-ray flare forecasts • Magnetopause crossing forecasts based on L1 data • EUV index 2006; not priority ordered Space Weather Measurements: Capabilities and Needs

  10. Customer Growth: Demand New Products • Increasing customer needs for space weather information drove several new products • The demand for space weather products is growing even as we approach solar minimum • The NOAA Space Environment Center website is serving more than 250,000 unique customers per month from 150 countries…in solar minimum!
