研究随时间变化的太阳活动区形态及其与爆发事件的关系，需要分析在多个波长域获得的具有不同空间和时间分辨率的成像数据，最好结合三维物理模型。为了实现这一目标，我们对我们基于IDL的仿真工具GX_Simulator进行了重大改进，GX_Simulator以前是为模拟来自耀斑环路的微波和X射线发射而开发的，使其能够模拟来自太阳AR的静态发射。该框架包括用于建立大气模型的新工具和用于计算包括新波长的排放的增强例程。在本文中，我们使用我们的升级工具来建模和分析AR，并将合成的排放图与观测结果进行比较。我们的结论是，模拟的磁热结构是一个相当好的近似的真实的。
The study of time-dependent solar active region (AR) morphology and its relation to eruptive events requires analysis of imaging data obtained in multiple wavelength domains with differing spatial and time resolution, ideally in combination with 3D physical models. To facilitate this goal, we have undertaken a major enhancement of our IDL-based simulation tool, GX_Simulator, previously developed for modeling microwave and X-ray emission from flaring loops, to allow it to simulate quiescent emission from solar ARs. The framework includes new tools for building the atmospheric model and enhanced routines for calculating emission that include new wavelengths. In this paper, we use our upgraded tool to model and analyze an AR and compare the synthetic emission maps with observations. We conclude that the modeled magneto-thermal structure is a reasonably good approximation of the real one.
