AI 中文摘要

监测长期色球活动及暗条、谱斑等大尺度太阳结构,对理解太阳磁周期和预测空间天气事件至关重要。光球磁场已被常规测绘,但H-α观测中一直缺乏色球结构的一致全球参考。本技术报告全面描述了利用NSO全球振荡网络组(GONG)H-α积分卡林顿综合图构建方法,该图源自全日面观测,概述了将这些观测转化为按卡林顿经度和正弦纬度分箱的720×360像素图的处理流程,并说明了最终数据产品的特征。

英文摘要

Monitoring long-term chromospheric activity and large-scale solar structures like filaments and plages is critical for understanding solar magnetic cycles and predicting space-weather events. While photospheric magnetic fields are routinely mapped, a consistent, global reference for chromospheric structures has been absent from H-$α$ observations. This technical report provides a comprehensive description of the methodology used to construct the NSF Global Oscillations Network Group (GONG) H-$α$ Integral Carrington Synoptic Maps from full-disk observations. We outline the processing pipeline developed to transform these observations into 720 x 360 pixel maps binned by Carrington longitude and sine(latitude) and describe characteristics of the final data product.
