SORCE Combined XPS, SOLSTICE, and SIM Solar Spectral Irradiance 24-Hour Means V001 (SOR3D_COMBINED_001) at GES DISC

Published by NASA/GSFC/SED/ESD/TISL/GESDISC;UCO/LASP/SORCE | National Aeronautics and Space Administration | Catalog Last Checked: June 25, 2026 at 01:41 PM | Dataset Last Updated: June 23, 2026
The SORCE Combined XPS, SOLSTICE, and SIM Solar Spectral Irradiance 24-Hour Means product consists of daily averages of the solar spetra from 0.1 to 2412 nm. The SORCE instruments make measurements during each daytime orbit portion, 15 orbits per day. This product combines data from the XPS, SOLSTICE and SIM instruments and merges them into a daily averaged solar spectra. The spectral resolution of SIM varies between 1-34 nm, SOLSTICE is 1 nm, and XPS is 7 nm. The SORCE combined data are arranged in a single file in a tabular ASCII text file which can be easily read into a spreadsheet application. The columns contain the date (calendar and Julian Day), min wavelength, max wavelength, instrument mode, input data version, spectral irradiance, irradiance uncertainty, and a data quality flag. Each row represents a separate day and wavelength.
