耀斑辐照度光谱模型（FISM）是一个重要的工具，估计太阳的变化，为无数的空间天气研究和应用，和FISM版本2（FISM 2）最近发布。FISM 2是一个太阳紫外线辐照度的经验模型，用于填补卫星观测中的光谱和时间空白。FISM 2估计太阳紫外线辐照度的变化，由于太阳活动周期，太阳自转和太阳耀斑。FISM 2提供的主要改进是，它基于多个新的，更精确的仪器，现在已经捕获了几乎一个完整的太阳周期和数千个耀斑，大大提高了模拟的FISM 2太阳辐照光谱的准确性。具体来说，这些新仪器是太阳动力学天文台（SDO）/极紫外线变率实验（EVE），太阳辐射和气候实验（SORCE）/X射线光度计系统（XPS）和SORCE/太阳恒星辐照度比较实验（SOLSTICE）。FISM 2还在相同的0至190 nm光谱范围内改进为0.1 nm光谱箱，并已用于研究估计由于行星热层和电离层中的太阳辐照度变化而引起的空间天气变化。
The Flare Irradiance Spectral Model (FISM) is an important tool for estimating solar variability for a myriad of space weather research studies and applications, and FISM Version 2 (FISM2) recently was released. FISM2 is an empirical model of the solar ultraviolet irradiance created to fill spectral and temporal gaps in the satellite observations. FISM2 estimates solar ultraviolet irradiance variations due to the solar cycle, solar rotations, and solar flares. The major improvement provided by FISM2 is that it is based on multiple new, more accurate instruments that have now captured almost a full solar cycle and thousands of flares, drastically improving the accuracy of the modeled FISM2 solar irradiance spectra. Specifically, these new instruments are the Solar Dynamics Observatory (SDO)/Extreme Ultraviolet Variability Experiment (EVE), Solar Radiation and Climate Experiment (SORCE)/X‐ray Photometer System (XPS), and SORCE/Solar Stellar Irradiance Comparison Experiment (SOLSTICE). FISM2 is also improved to 0.1‐nm spectral bins across the same 0‐ to 190‐nm spectral range and is already being used in research to estimate space weather changes due to solar irradiance variability in planetary thermospheres and ionospheres.
