Solar Models

NRL SSI - A solar spectral irradiance (SSI) model, empirically derived using sunspot area proxies

FISM (Flare Irradiance Spectral Model) - An empirical model of the solar irradiance spectrum, 0.1 nm - 190 nm at 1 nm resolution

SRPM - A model of the solar spectrum, 200 nm - 100 µm, computed by the Solar Radiation Physical Modeling (SRPM) v2 system

Solar Radiation Physical Modeling (SRPM) Image Masks - A filter to isolate sunspot umbral and penumbral pixels, and images to separate the facular (bright plage), plage, active network, network, and quiet Sun components
