This research program will develop a method for assimilating energetic particle data from satellites into the empirical CRRES-ELE model for outer belt energetic particles. The data assimilation technique to be used is a form of "nudging" that is commonly used in assimilating data into terrestrial weather models. The technique has already been shown to reduce the error in the CRESS-ELE model by as much as an order of magnitude. The goal of the program will be to produce a model of outer belt energetic particles that is 80% accurate under all conditions. The outputs of the model will be tailored for use by the NOAA Space Environment Center and the Air Force 55th Space Weather squadron.

这项研究计划将开发一种方法，将来自卫星的高能粒子数据同化到外带高能粒子的经验CRRES-ELE模型中。将使用的数据同化技术是一种“轻推”形式，通常用于将数据同化到陆地天气模式中。这项技术已经被证明可以将Cress-Ele模型中的误差减少一个数量级。该计划的目标将是产生一个在所有条件下都是80%准确的外带高能粒子模型。该模型的输出将为NOAA空间环境中心和空军第55空间天气中队量身定做。
