Abstract
The near-earth radiation and plasma environment consists of diverse particle populations of different origins that often evolve dynamically over time and space, and span a broad energy range. Such an environment poses challenges from both science and space weather-impact perspectives. It brings about detrimental effects on spacecraft electronics, materials, and can pose a significant health challenge for life in space. As part of the COSPAR/ISWAT (International Space Weather Action Teams) initiative (https://www.iswat-cospar.org/g3), these environments fall into the G3 Cluster, which has intimate connections with other clusters (e.g., solar drivers and other aspects of geospace). The space weather impacts from populations of the near-Earth region include surface charging, internal charging, single event effects, total dose, polar cap absorption of high frequency radio communications, radiation effects on aviation, and impacts on future human activities in and/or traversing the region. In this presentation, we will review recent progress with regard to all these different particle populations and their modeling efforts and, to the degree possible, identify those with real-time or forecasting capabilities. We will discuss knowledge and modeling gaps and what is needed in further uniting science and end-user communities. We will list our recommendations for steps to be taken during the next 5-10 years so that better decision-making products and tools for end users can be achieved, while at the same time advancing scientific understanding.
