Because the doses received on-board aeroplanes are now monitored to fulfil legal requirements in some countries, including the European Community, the models to calculate doses received during solar events have left their purely academic status to become a part of operational systems as well. The present work considers parameters of importance to determine the doses received during solar events: spectral characteristics of the solar particles and anisotropy of primary particles and their variations in the course of the Ground Level Enhancement (GLE). Precise determination of both, using all the information available from the worldwide neutron monitor network, being a long process, simpler methods are proposed to calculate rigidity spectrum exponent and to correct the models for anisotropy. A recent GLE of large intensity, having occurred on 20 January 2005, is used both as an example of an important event and because the necessary data were collected within a few days, showing that the above methods, in addition to their own interest, have also an operational potential.
由于目前在一些国家（包括欧洲共同体），飞机上所接受的剂量受到监测以满足法律要求，因此用于计算太阳事件期间所接受剂量的模型已不再仅仅具有学术地位，还成为了运行系统的一部分。本研究考虑了确定太阳事件期间所接受剂量的重要参数：太阳粒子的光谱特征、初级粒子的各向异性及其在地面增强（GLE）过程中的变化。利用全球中子监测网络提供的所有可用信息精确确定这两者是一个漫长的过程，因此提出了更简单的方法来计算刚度谱指数并校正各向异性模型。2005年1月20日发生的一次高强度近期GLE事件，既被用作一个重要事件的示例，也因为在几天内收集到了必要的数据，这表明上述方法除了自身的价值外，还具有实际应用潜力。
