The variation in the spectral irradiance of the Sun influences the temperature and
chemistry within the Earth's atmosphere. The semi-empirical SATIRE-S model has
demonstrated remarkable agreement with observations of total solar irradiance. By design,
the model computes spectral solar irradiance (SSI) and here we present a new, consistent SSI
dataset that spans 35 years from 1974 to 2009. We describe the construction of the dataset
and show comparisons with the NRLSSI model and observations from UARS and SORCE.
