QinetiQ大气辐射模型（QARM）中包含了各种模型，以计算主要太阳粒子事件期间的增强情况以及任何同时发生的降低截止刚性的地磁暴的影响。预测与可用的飞行中的测量结果进行比较，并扩展到最坏情况下的估计数的飞机航线。结果表明，在太阳粒子事件中，粒子通量随高度和地磁纬度的梯度非常陡，剂量和注量对地磁条件和路径都非常敏感。
Models have been embodied within the QinetiQ atmospheric radiation model (QARM) to compute enhancements during major solar particle events and the influence of any concurrent geomagnetic storms that lower the cut-off rigidity. Predictions are compared with available in-flight measurements and extended to give worst case estimates for a number of aircraft routes. It is found that during solar particle events the gradients of particle fluxes with respect to altitude and geomagnetic latitude are so steep that doses and fluences are extremely sensitive to both geomagnetic conditions and the exact route.
