SORCE Solar Spectral Irradiance - Time Series
The SORCE spacecraft has been measuring solar spectral irradiance (SSI, W/m^2/nm) since shortly after the SORCE launch in early 2003. This data set includes daily averaged SSI measurements from three instruments:
- Spectral Irradiance Monitor (SIM): 310-2400 nm (Release Notes)
- SOLar STellar Irradiance Comparison Experiment (SOLSTICE): 115-310 nm (Release Notes)
- XUV Photometer System (XPS): 0.1-40 nm (Release Notes)
For more information about this data set, see the SORCE web site.
