We study the impact of enhanced solar flare radiation on the low- to mid-latitude ionosphere. The methodology is to develop an EUV irradiance spectrum based upon observations that can be used in the NRL ionosphere model SAMI3. Since solar irradiance observations typically do not have the cadence necessary to follow the evolution of a flare, we have developed techniques for computing flare spectra from the available solar data. The initial simulation study will use a generic flare radiation spectrum to test the technique and develop a baseline understanding of the impact of flare radiation on the ionosphere. Subsequent studies will ingest flare spectra based on actual events and model results will be compared to observations if available. A previous study of the Bastille Day storm found that flare radiation can increase the F-region ionosphere density by up to 50% [Meier et al., Geophys. Res. Lett. 29, 10.1029/2001GL013956, 2002].
