Additional Information

The Solar Irradiance Platform spectrum

The Solar Irradiance Platform full solar spectrum provides 1 nm resolution from the X-rays to the far infrared wavelengths. Other formats include the aeronomy community's SC21REFW 0.1 nm format as well as the Torr and Torr 39 wavelength groups and lines. The daily time resolution is available historically back to February 14, 1947 and forecast out to 5 solar cycles. Around the time of the current epoch, hourly solar proxy values are produced and placed into one of eight 3-hour bins for each day from -48 to +72 hours. These time bins correspond to the ap geomagnetic index bins and the 5-day/3-hourly format is used for high time resolution space operations centered on the current epoch. As new upgrade versions of Solar Irradiance Platform are provided, there is improved accuracy and variability in different spectral regions.

Solar Irradiance Platform Applications

Solar Irradiance Platform full spectral irradiances and integrated irradiance proxies can be used for a wide variety of applications:

  • Historical databases of solar influence on the perturbed thermosphere and ionosphere
  • Post-event analysis for satellite anomalies and HF radio communications
  • LEO satellite mission planning activities
  • Orbit debris removal validation
  • Theater-of-operations capability assessments.

Other capabilities of the Solar Irradiance Platform model include:
