Big Data Processing and Modeling in Solar Physics

Abstract

!e Sun is the energy source of the Earth. !e electromagnetic environment of the Earth is affected by solar activity, and the impact of violent activity bursts can reach the Earth within eight minutes. Hence the detection, recognition, and prediction of solar activity are essential. !e physical mechanisms of solar activity bursts are not yet completely clear. However, a large number of data have been accumulated and solar observation instruments can record the multiwavelength imaging data every day with high cadence. In order to cope with the rapidly growing amount of solar data, there is an increasing need for automatic detection and prediction technologies. !is special issue is focused on solar data mining technology. We invited authors to contribute with original research articles in this special issue. Eleven original research manuscripts have been received. After the peer-reviewed process, seven of them were accepted for publications. !erein, three papers focused on the detection and recognition of regions of interest in the solar images, two papers presented research on the short-term and midterm solar activity prediction, respectively, and one paper discussed the influence of solar activity on economic activities. From these articles, we can find that the machine learning methods, especially the deep learning methods, play an important role in solar activity monitoring and prediction. Finally, we hope that researchers will find this special issue useful. Conflicts of Interest
