SORCE SOLSTICE FUV Level 3 Solar Spectral Irradiance Daily Means V018 (SOR3SOLFUVD) 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 01:31 PM | Dataset Last Updated: June 23, 2026
Version 018 is the final version of this data product, and supersedes all previous versions. The SORCE SOLSTICE Far-UV Solar Spectral Irradiance (SSI) data product SOR3SOLFUVD is constructed using measurements from the SOLSTICE FUV instrument, which are combined into merged daily solar spectra over the spectral range from 115 to 180 nm at a spectral resolution of 1 nm. Irradiances are reported at a mean solar distance of 1 AU and zero relative line-of-sight velocity with respect to the Sun. The SOLSTICE absolute uncertainty better than 5%. All of the SOR3SOLFUVD 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, Julian day, minimum wavelength, maximum wavelength, instrument mode, data version number, irradiance value, irradiance uncertainty, and data quality. The rows are arranged with data at each wavelength over the full SOLSTICE FUV wavelength range, repeating for each day for the length of the measurement period.
