AB: The Flare Irradiance Spectral Model (FISM) is an empirical model of the solar irradiance spectrum from 0.1 to 195 nm at 1nm resolution and on a 1-minute time cadence. This model is based on the TIMED SEE data and uses the MgII core-to-wing ratio and GOES XRS data as proxies. FISM accounts for the significant irradiances changes due to solar flares, which includes orders of magnitude increases in the X-rays to factors of two increases in the EUV. The need for FISM arises due to the lack of solar irradiance measurements on minute time scales for the entire XUV and EUV spectral region, and currently available daily models and measurements do not represent or include the irradiance changes due to solar flares. Algorithms and current results from FISM will be discussed, as well as the future improvements that are planned for the model.
