Overview

This is the `Active Region database for Influence on Solar cycle Evolution (ARISE)', developed by Ruihui Wang, Jie Jiang, and Yukun Luo, Beihang University, China.

The database covers ARs from Carrington Rotations (CRs) 1909 to 2303, corresponding to the period from May 1996 to October 2025, encompassing cycles 23, 24, and 25. Data from subsequent CRs will be continuously added.

ARmaps.zip contains the outputted low-resolution (180*360) maps of detected AR. The AR maps are named according to their emergence time relative to the specified time0 (default: CR 1912, 1996-07-25 21:35:44.193). ARmaps(Luo2026).zip contains the AR maps used in the work of Luo 2026.

We offer two versions of the database: one includes all detected ARs (database_allAR.xlsx), and the other excludes repeat ARs (database_remove_repeat_AR.xlsx). Both versions contain the same parameters, including basic parameters and those related to solar cycle variability (dipole fields, calculated with $\lambda_R = 6.44^\circ$). However, caution should be taken when using the dipole field data from database_allAR.xlsx, as some long-lived ARs are recorded multiple times.

For a detailed explanation of the purpose and design of the database, please refer to the GitHub repository (https://github.com/Wang-Ruihui/A-live-homogeneous-database-of-solar-active-regions) and the following publications:
