This research will contribute to the development of a robust time-distance analysis and inversion methodology to use the solar acoustic oscillations to infer the three-dimensional subsurface structure of magnetic flux concentrations rising from the solar interior. It will permit one to better characterize the actual diagnostic potential of the method and to better understand the biases in the inferred solutions introduced by the topology of the associated annihilator, while addressing trade-off issues between resolution in space and time versus error magnification. Such a development of time-distance analysis techniques is a key element needed to maximize the scientific return of the upgraded Global Oscillation Network Group (GONG) instruments, and it also offers the potential of a long-range forecasting tool for the National Space Weather Program.

这项研究将有助于开发强大的时距分析和反转方法，以使用太阳声振荡来推断从太阳能内部升高的磁通量浓度的三维地下结构。 它将允许人们更好地表征该方法的实际诊断潜力，并更好地了解相关歼灭者拓扑引入的推断解决方案中的偏见，同时解决时空和时间分解与误差放大之间的折衷问题。 这种时间距离分析技术的这种开发是最大程度地提高升级的全球振荡网络组（GONG）仪器的科学回报所需的关键要素，并且还为国家太空天气计划提供了长期预测工具的潜力。
