SORCE version 2 level 3 data files are now available. Please review the Data Quality Information Summary before using.

Welcome to the SORCE data support web site located at the NASA Goddard Earth Sciences (GES) Distributed Active Archive Center (DAAC). The GES DAAC will provide end-to-end support for all delivered data products from SORCE.

SORCE was launched successfully on January 25, 2003 aboard a Pegasus XL rocket into a 645 km altitude and 40° inclined orbit. SORCE is a key element in NASA's Earth Observing System (EOS) with the aim of measuring the solar radiation incident on the Earth's upper atmosphere. Management of SORCE is provided by the Labratory for Atmospheric and Space Physics (LASP), at the University of Colorado in Boulder.

The SORCE spacecraft includes four instruments: the Total Irradiance Monitor (TIM), the Solar Stellar Irradiance Comparison Experiment (SOLSTICE), the Solar Irradiance Monitor (SIM), and the soft X-ray Ultraviolet Photometer System (XPS). These instruments use state-of-the-art technology to provide more accurate spectral and total solar irradiance measurements compared to precursor sensors.

You may download the SORCE data or order these on tape media by selecting the "Data Access" link on the menu bar.
