SPEARHEAD

SPEcification, Analysis & Re-calibration of High Energy pArticle Data

About SPEARHEAD

Through a detailed analysis of very high-energy particle observations from the most important heliophysics missions combined with ground based measurements, SPEcification, Analysis & Re-calibration of High Energy pArticle Data – SPEARHEAD will provide answers to three science questions:

1

How are protons accelerated beyond 100 MeV and electrons beyond 1 MeV in solar eruptions?

2

What are the release times and spectral characteristics of near-relativistic particles from solar eruptions?

3

How do coronal and interplanetary structures affect the transport processes of very high energetic particles?

To enable the scientific data analysis SPEARHEAD has three technical objectives:

Determining the response functions of a large number of spacecraft instruments to derive high-energy particle fluxes from observations at unprecedented accuracy releasing revised and completely new datasets

Performing cross-calibration of datasets measured by science-grade and monitoring instruments to enable the use of monitoring data for scientific analyses

Combining high-energy particle and context observations together with modeling of plasma structures for easier in-depth analysis of solar eruptions, quantifying their effect and delivering them to the community
