Solar Radiation and Climate Experiment (SORCE) Collection 11 released

SORCE Total Solar Irradiance (TSI) Collection 11 data are now available;  the data set update was released on December 9, 2010. Please see the SORCE Data Access page at the GES DISC for instructions on downloading the data files.

The refinements to the data for Collection 11 are as follows:

  • Improved (and updated) dark irradiance algorithm and model (more accurately models the dark irradiance correction)
  • Updated degradation corrections using improved dark models for all cavities
  • Updated gain calibrations


Documentation is available from the Solar Radiation and Climate Experiment Web site, under the "Data" tab" .

SORCE Data Product Summary

Data from the SORCE mission has been in the news recently:

SORCE's Solar Spectral Surprise

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.

SORCE 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.
