Description:

This study aims to assess the performance of coronal models across multiple solar cycles and to analyze long-term variations in solar coronal structures observed in multiple EUV channels. To achieve this, we developed a comprehensive database of solar corona (data cubes) and inner heliosphere simulation outputs using the Alfvén Wave Solar atmosphere Model (AWSoM) within the Space Weather Modeling Framework (SWMF) for Solar Cycles 24 and 25 (SC24 and SC25). This database enables us to investigate the temporal evolution of solar wind source regions—Coronal Holes (CH) and Active Regions (AR). Model accuracy was assessed by comparing synthetic images with concurrent AIA observations in six EUV channels (94, 131, 171, 193, 211, and 335 Å). Additionally, we evaluated the reliability of AWSoM’s solar wind plasma outputs at 1 AU by comparing them with OMNI data for each Carrington Rotation (CR).
