2. Project Summary Solar Imaging
  • SUVI Algorithm Readiness
  • Provides key 1 to 3-day warning of geomagnetic
    storms and enhances of solar radiation storm
    forecasts by providing flare locations in lt 2
    minutes.
  • Primary customers include all SWx data users.
  • Example customer impacts include loss of Japans
    ADEOS-2 spacecraft at a cost of 640M, which
    carried NASAs Seawinds instrument at a cost of
    154M after a severe geomagnetic storm. Power
    blackout of 50000 customers in Sweden in 2003.

2. Project Summary EUV Irradiance
  • EUVS Algorithm Readiness
  • Measure the solar EUV energy input to the upper
    atmosphere and improve the ability to predict
    upper atmospheric and ionospheric conditions.
  • Primary customers include satellite operators
    (LEO), HF communications and GPS operators.
  • EUVS data and products are used to forecast
    satellite orbital lifetimes in LEO and to plan
    for satellite and other spacecraft maintenance
    and replacement.

2. Project Summary X-ray Irradiance
  • XRS Algorithm Readiness
  • XRS data drives Radio Blackout portion of NOAAs
    Space Weather Scales that is crucial to SWPC
    customers.
  • Major flares outshine the Sun in X-rays by 10,000
    times in a few minutes.
  • Every second counts to customers like airlines
    who need to direct aircraft to new radio
    frequencies or links before static overwhelms
    signals.
  • Radio blackouts result from rapid ionization of
    the D-region of the ionosphere causing
    increasingly higher HF frequencies to be
    absorbed.
  • Atmospheric ionization from a solar flare is
    almost instantaneous.
  • Related changes to the ionosphere degrade the
    accuracy of GPS systems impacting customers with
    operations such as precision deep sea drilling.

2. Project Summary Energetic Particles
  • SEISS (Radiation) Algorithm Readiness
  • SEISS data drives Solar Radiation Storm portion
    of NOAAs Space Weather Scales that is crucial to
    SWPC customers.
  • Products serve airline and satellite industries
    and manned space flight ops.
  • Electron radiation can cause surface and deep
    charging in spacecraft leading to damaging
    discharges.
  • Proton radiation causes single event upsets and
    noise on detectors.
  • Heavy ion radiation is a health risk to
    astronauts and aviators flying at high altitudes
    or latitudes.
  • Particle precipitation along Earths magnetic
    field lines at the poles causes D-region
    ionization leading to radio blackouts for polar
    airline flights.

2. Project Summary Magnetic Field Environment
  • Magnetometer Algorithm Readiness
  • Only measure of geomagnetic storm impact at
    geosynchronous orbit.
  • Key for interpreting solar radiation storm
    measurements by SEISS.
  • Primary operational customers are satellite
    operators, who, for example had to implement
    manual attitude control for a number of TV and
    Pay Radio satellites due to magnetopause
    crossings during October 2003 storms.
  • Key for validating predictive Sun-to-Earth
    numerical models
