This project is a collaborative effort with scientists at the Los Alamos National Laboratory to develop a real-time model for specifying and forecasting the state of Earth's radiation belt. The project will utilize data assimilation methods in conjunction with physical models and modern machine learning techniques to examine the acceleration, transport and loss processes for energetic electrons in the radiation belt. The resulting model will include confidence limits on the system-wide forecasts, making the results useful for operational space weather predicitions. The project will benefit society by making improved radiation-belt predictions at reduced operational costs and the forecasts will be made freely available online.The project includes a strong educational and teaching component through the participation of graduate students at the University of Colorado. In addition the research will be integrated with the Los Alalmos Space Science Outreach (LASSO) program, which offers teacher training to underrepresented groups and individuals with disabilities.

该项目是与洛斯阿拉莫斯国家实验室的科学家合作开发的实时模型，用于指定和预测地球辐射带的状态。 该项目将利用数据同化方法结合物理模型和现代机器学习技术来检查辐射带中高能电子的加速、传输和损失过程。 由此产生的模型将包括对全系统预报的置信限制，使结果可用于业务空间天气预测。 该项目将以降低运营成本的方式改进辐射带预测，从而造福社会，并且预测结果将在网上免费提供。该项目包括科罗拉多大学研究生参与的强大的教育和教学内容。 此外，该研究还将与洛斯阿拉莫斯空间科学外展（LASSO）计划相结合，该计划为代表性不足的群体和残疾人提供教师培训。
