摘要:

在本文中,我们以适合机器学习研究的格式展示了来自NASA太阳动力学天文台(SDO)任务的精选数据集。从1级科学产品开始,我们已经处理了各种仪器校正,下采样到可管理的空间和时间分辨率,并在空间和时间上同步观测。我们说明了使用这个数据集与两个示例应用程序:预测未来的EVE辐照度从目前的EVE辐照度和翻译HMI观测到AIA观测。对于每个应用程序,我们都提供了指标和基线,以便将来进行模型比较。我们预计,这个精心策划的数据集将促进太阳物理学和物理科学领域的机器学习研究,增加SDO任务的科学回报。这项工作是2018年NASA前沿发展实验室计划的直接结果。请参阅附录获取数据集。

英文摘要:

In this paper we present a curated dataset from the NASA Solar Dynamics Observatory (SDO) mission in a format suitable for machine learning research. Beginning from level 1 scientific products we have processed various instrumental corrections, downsampled to manageable spatial and temporal resolutions, and synchronized observations spatially and temporally. We illustrate the use of this dataset with two example applications: forecasting future EVE irradiance from present EVE irradiance and translating HMI observations into AIA observations. For each application we provide metrics and baselines for future model comparison. We anticipate this curated dataset will facilitate machine learning research in heliophysics and the physical sciences generally, increasing the scientific return of the SDO mission. This work is a direct result of the 2018 NASA Frontier Development Laboratory Program. Please see the appendix for access to the dataset.
