Understanding the energetic particle or radiation environment in the inner heliosphere is critical to two communities: space system designers and space system operators. To design space systems for safe and reliable performance, designers need specific reference environments, typically corresponding to the most severe conditions expected at some confidence level during a mission. By contrast, space situational awareness in realtime is essential to assure the safety of performance of space systems, missions, and crews. As discussed in a report to the NASA JSC Space Radiation and Analysis Group (SRAG) , a physics-based capability to address both needs does not yet exist. These needs go to the heart of the National Space Weather Program aim of predicting space weather disturbances (the consequence of which is a highly disturbed radiation environment) and communicating that information to those most impacted. Over the past decade, we have developed a unique suite of research and operational tools that are positioned to be transitioned to an operational toolset capable of addressing these strategic needs for both user communities. We have proposed to develop a strategic capability that describes for the first time the full temporal and spatial radiation environment of the inner heliosphere, using developed and mature physics-based models and codes. We envision our toolset providing the fundamental radiation capability in an eventually comprehensive and publicly available space weather system.
