SORCE Total Solar Irradiance (TSI) Collection 10 data are now available. Please see the Data Access page for instructions on downloading the data files.
Documentation is available from the SOlar Radiation and Climate Experiment Web site, under the "Data" tab.
If you haven't heard of SORCE before, the following is a short description of the mission from the SORCE home page:
"The Solar Radiation and Climate Experiment (SORCE) is a NASA-sponsored satellite mission that is providing state-of-the-art measurements of incoming x-ray, ultraviolet, visible, near-infrared, and total solar radiation. The measurements provided by SORCE specifically address long-term climate change, natural variability and enhanced climate prediction, and atmospheric ozone and UV-B radiation. These measurements are critical to studies of the Sun; its effect on our Earth system; and its influence on humankind.
The SORCE spacecraft was launched on January 25, 2003 on a Pegasus XL launch vehicle to provide NASA's Earth Science Enterprise (ESE) with precise measurements of solar radiation."
