MAIRE: Incident Spectrum

The incident spectrum defines the incident particles of MAIRE at the top of the atmosphere (100 km). Initially this spectrum does not include the influence of geomagnetic shielding, but a cutoff is then determined and applied by MAIRE internally for the user specified location and date.

The incident particles at the top of the atmosphere are the source of the radiation in the atmosphere. The type of incident particle in MAIRE can be:

• Cosmic ray protons and alphas.
  • the spectrum can be determined by MAIRE using the built-in cosmic radiation model.
  • the spectrum can be calculated with an external model and input into MAIRE as a user defined spectrum.
• Cumulative solar proton fluence spectrum.
• Ground level solar proton events.
• User defined spectrum.
