The SIRE2 Toolkit

The Space Ionizing Radiation Environment and Effects (SIRE2) toolkit has been developed to update and extend the tools used by the space and radiation effects community. It includes new environment models, the capability to examine how the environment changes along satellite and other trajectories and batch processing capabilities for both environments and radiation effects on electronics. An overview of the capabilities in the SIRE2 Toolkit is provided, and examples of applying SIRE2 to satellite orbits and arbitrary trajectories are given. Key Points The calculation options include legacy models, the latest models, and batch calculations of space radiation environments and radiation effects The tools allow space radiation environment calculations on segments of orbits and on arbitrary spacecraft trajectories SIRE2 provides a new probabilistic model for solar energetic particle peak flux
