In HESPERIA, a real-time tool for predicting 30-50 MeV SEP events by using the REleASE scheme, will be implemented. The tool will provide advanced nowcasting/forecasting methods based on the approach developed by Posner (2007). The proton time profiles at 30-50 MeV will be inferred based on near relativistic and relativistic electron intensity time profiles measured by SOHO/EPHIN and ACE/EPAM.

The final goal is to infer the maximum proton intensity and onset close to Earth.

Within HESPERIA, UMASEP will focus on the implementation and evaluation of a real-time predictor of SEP events with E > 500 MeV by using the UMASEP scheme, which correlates solar data and near-Earth radiation data. This work will need different steps:

  • explore several input data types related to high energy particles recorded on the ground and onboard satellites
  • development of a High-Energy Data Adaptor that communicate with the HESPERIA UMASEP's core
  • testing activities 

For the case of real-time solar data, this effort will explore SXR, HXR, and radio data., while for the case of real-time near-Earth radiation data neutron monitor and GOES/HEPAD data will be utilized.
