本文描述了我们用来重建FUV和EUV辐照度光谱的物理模型的更新，以及在任何给定时间点可能覆盖太阳盘的特征的辐射光谱，这取决于太阳活动的状态。目前的更新介绍了重要的修改色球日冕过渡区的所有模型。此外，更新引入了改进和扩展的原子数据。通过这些变化，计算和观察到的光谱的协议在很大程度上提高了许多EUV线重要的地球高层大气的建模。本文介绍了改进，并显示与EUV/FUV辐射率和辐照度测量的详细比较。在另一篇文章中讨论了这些模型在波长超过200 nm时的太阳光谱辐照度。
This article describes an update of the physical models that we use to reconstruct the FUV and EUV irradiance spectra and the radiance spectra of the features that at any given point in time may cover the solar disk depending on the state of solar activity. The present update introduces important modifications to the chromosphere–corona transition region of all models. Also, the update introduces improved and extended atomic data. By these changes, the agreement of the computed and observed spectra is largely improved in many EUV lines important for the modeling of the Earth’s upper atmosphere. This article describes the improvements and shows detailed comparisons with EUV/FUV radiance and irradiance measurements. The solar spectral irradiance from these models at wavelengths longer than ≈ 200 nm is discussed in a separate article.
