This book describes the state-of-the art instruments for measuring the solar irradiance from soft x-ray to the near infrared and the total solar irradiance. Furthermore, the SORCE mission and early results on solar variability are presented along with papers that provide an overview of solar influences on Earth. This collection of papers provides the only detailed description of the SORCE mission and its instruments.
