论文摘要
可见光谱范围内太阳的观察属于地面和空间中的仪器获得的标准测量。如今，几乎连续的全盘观察中有中等分辨率和高空间，光谱和/或时间分辨率的专门运动构成了一种圣杯，用于研究，可以捕捉（）太阳氛围的动态和能量的长期和短期变化。对光电光谱线的观察结果使我们不仅可以估计小区域的强度，还可以估算各种衍生的数据产品，例如多普勒速度和/或磁场矢量的组件。我们表明，这些测量值不仅包含有关太阳表面太阳等离子体动力学的直接信息，还包含下方和上方区域的烙印。在这里，我们讨论了两个示例：首先，局部时间距离的热疗学是近地下中血浆动态诊断的工具，其次是在耀斑期间确定太阳大气结构的确定。在这两种情况下，该方法都涉及反向建模的技术。
Observations of the Sun in the visible spectral range belong to standard measurements obtained by instruments both on the ground and in the space. Nowadays, both nearly continuous full-disc observations with medium resolution and dedicated campaigns of high spatial, spectral and/or temporal resolution constitute a holy grail for studies that can capture (both) the long- and short-term changes in the dynamics and energetics of the solar atmosphere. Observations of photospheric spectral lines allow us to estimate not only the intensity at small regions, but also various derived data products, such as the Doppler velocity and/or the components of the magnetic field vector. We show that these measurements contain not only direct information about the dynamics of solar plasmas at the surface of the Sun but also imprints of regions below and above it. Here, we discuss two examples: First, the local time-distance helioseismology as a tool for plasma dynamic diagnostics in the near subsurface and second, the determination of the solar atmosphere structure during flares. The methodology in both cases involves the technique of inverse modelling.
