Scientific paper
Space weather is undergoing a major transformation whereby the demand for decision-capable information is beginning to far exceed our ability to produce the needed information. The limitations in our space weather capabilities are due to a number of factors, including a sparsity of data, limitations in our ability to assimilate data into our models, and the difficulties in modeling the diversity of scales and processes that control the solar-terrestrial environment. The increasing demand for space weather information creates the imperative to focus our research not only on improving our understanding of basic physical processes, but also on achieving specific outcomes that yield near-term progress in areas of high demand. Whereas, for example, full-physics, kinetic-global codes of particle acceleration and magnetic reconnection are important long-term goals, efforts to parameterize the sub-grid-scale physics or to implement intermediate solutions could lead to important near-term improvements in mitigating space weather impacts, as well as improve our understanding of the physical processes. This presentation will summarize the major areas where space weather information is needed, and discuss areas where advances in kinetic-global model development could have the most immediate impact on space weather services.
