Space Weather: Applications of Global Oscillations Network Group (GONG+) Magnetograms

全球振荡网络组(GONG)磁图将被用作研究太阳光球层磁场演化及其与日冕物质抛射(CME)关系的主要数据集。利用GONG资料建立位场-源-面(PFSS)日冕模式，以确定内边界条件。这些将构成合成专门天气图的基础，目的是(1)确定源表面磁中性线的位置，(2)根据Wang-Sheeley模型预测太阳风特征，以及(3)划定开放和封闭磁场区的演化。这些信息将在一个实时更新的网站上公布，并提供给美国国家海洋和大气局/空间环境中心的网站。这项工作对于理解活动区的出现和碎裂对大尺度日冕磁场演化的影响至关重要。

Global Oscillations Network Group (GONG+) magnetograms will be employed as the principal data set to study the evolution of the solar photospheric magnetic field, and its relationship with coronal mass ejections (CMEs). Potential-field source-surface (PFSS) coronal models will be constructed using the GONG+ data to specify the inner boundary condition. These will form the basis for the synthesis of specialized synoptic maps aimed at, (1) establishing the location of source surface magnetic neutral lines, (2) predicting solar wind characteristics based on the Wang-Sheeley model, and (3) delineating the evolution of open and close magnetic field regions. This information will be posted on a real time updated web site and delivered to the NOAA/Space Environment Center website. This effort will be essential for understanding the impacts of active region emergence and fragmentation on the evolution of the large-scale coronal magnetic field.
