AB: The SORCE SIM and TIM instruments have been making concurrent measurements of the total and spectral solar irradiance (TSI and SSI, respectively) since August 2003 up to the present solar minimum time frame. The SIM instrument measures spectral irradiance in the 200-2400 nm region covering 97.6 percent of the TSI with a resolving power ranging from 280 in the near UV to a minimum of 37 at 1260 nm. With this full spectral coverage, the spectral irradiance time series can be integrated into sub-ranges and compared to the TSI record, showing that different spectral regions provide different components to the total record with some offsetting long-term trends. The SIM SSI record also provides excellent information that is used to study the wavelength dependent components of solar variability models and input for studies of Earth atmospheric heating.
