地面磁场扰动预报的数据模型验证,特别是地表磁场变化的时间速率(dB/dt),是模型开发和减轻地磁感应电流效应的关键任务。虽然目前存在一个社区接受的dB/dt验证标准(Pulkkinen等人,2013),它有几个限制,阻止更完整的理解模型的能力。这项工作提出了国际空间天气能力评估论坛地面磁扰动工作组的建议,以创建下一代验证套件。四个建议,以解决现有的套件:大大扩大地面观测站的数量,扩大包括在套件中的事件的数量从六个到八个,生成指标作为一个功能的磁本地时间,并生成指标作为一个功能的活动类型。对于每一个,实施细节进行了探讨。限制和未来的考虑也进行了讨论。
Data‐model validation of ground magnetic perturbation forecasts, specifically of the time rate of change of surface magnetic field, dB/dt, is a critical task for model development and for mitigation of geomagnetically induced current effects. While a current, community‐accepted standard for dB/dtvalidation exists (Pulkkinen et al., 2013), it has several limitations that prevent more complete understanding of model capability. This work presents recommendations from the International Forum for Space Weather Capabilities Assessment Ground Magnetic Perturbation Working Team for creating a next‐generation validation suite. Four recommendations are made to address the existing suite: greatly expand the number of ground observatories used, expand the number of events included in the suite from six to eight, generate metrics as a function of magnetic local time, and generate metrics as a function of activity type. For each of these, implementation details are explored. Limitations and future considerations are also discussed.
