SOHO/Energetic and Relativistic Nuclei and Electron (ERNE) Data Archive

The Energetic and Relativistic Nuclei and Electron (ERNE) Sensor Unit
(ESU) has two energetic particle sensors: LED and HED.

ERNE will investigate the solar atmosphere by detecting charged
particles produced in various solar energy release processes.

The scientific objectives of the experiment are:

1. energy spectra of ions and electrons above 1 MeV/nucleon
2. elemental and isotopic abundance H to Fe
3. particle acceleration in the solar atmosphere and interplanetary
shocks
4. particle propagation in the solar corona and in the
interplanetary space
5. study both large and small scale properties of the IMF
6. short-period temporal variations of particle flux
7. flux anisotropy within the apparatus viewing cone
8. flux of protons penetrating the instrument (even decay solar
neutrons)

Data consists of two-hour averaged Proton and Helium intensities, data
archived by Carrington rotation, HED Proton events in the energy range
12-100 MeV and Level-2 EXPORT data.
