资源简介：
本数据集由奥卢大学空间气候研究室创建，基于SOHO/EIT和SDO/AIA的完整日面图像，旨在展示太阳表面不同EUV辐射的分布。数据集包含307个SOHO/EIT日面图和116个SDO/AIA日面图，覆盖1996年至2018年，提供四种EUV波长的系统性和均质性视图。数据集创建过程中，通过标准化强度尺度构建日面图，以消除由于传感器退化导致的EIT和AIA EUV强度的显著和复杂漂移。该数据集适用于研究长期日冕洞演化等科学问题。
This dataset was developed by the Space Climate Research Group of the University of Oulu, based on full-disk solar images from SOHO/EIT and SDO/AIA, and is intended to illustrate the distribution of different EUV radiations on the solar surface. It contains 307 full-disk solar images from SOHO/EIT and 116 from SDO/AIA, covering the period from 1996 to 2018, and provides systematic and homogeneous visualizations for four EUV wavelengths. During the dataset construction process, full-disk images were calibrated using standardized intensity scales to eliminate significant and complex drifts in the EUV intensities of EIT and AIA caused by sensor degradation. This dataset is suitable for scientific research such as studies on the long-term evolution of coronal holes.
