SORCE SIM Level 3 Solar Spectral Irradiance Daily Means V027 (SOR3SIMD) at GES DISC
Version 027 is the final version of this data product, and supersedes all previous versions. The SORCE SIM Solar Spectral Irradiance (SSI) data product SOR3SIMD is constructed using measurements from the SIM instruments, which are combined into merged daily solar spectra over the spectral range from 240 to 2413 nm at a spectral resolution ranging from 1 to 27 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 SIM absolute uncertainty is about 2%. All of the SOR3SIMD 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 SIM wavelength range, repeating for each day for the length of the measurement period.

Version Description
SOR3SIMD Version 027 is the final version of this data product, and supersedes all previous versions. Please see the SORCE SIM Release Notes for detailed description and differences for this and previous versions. Version 027 - released 12 Nov 2020 - doi:10.5067/LDDKZ3PXZZ5G Data availability: 2003/04/14 to current. Employs the same correction methodology as in version 026. Version 026 - released 10 Jan 2020 - doi:10.5067/IGSTXAANZ79N Data availability: 2003/04/14 to current. Employs the same correction methodology as in version 025. Version 025 - released 26 Nov 2018 - doi:10.5067/0EQZJBS6B39C Data availability: 2003/04/14 to 2019-12/31. Employs the same correction methodology as in version 024. Diode temperature correction coefficients have been rederived for all diodes. UV-VIS gap from 306-310 has been eliminated. Version 024 - released 29 May 2018 - doi:10.5067/4VB69K91U39I Data availability: 2003/04/14 to 2018/05/21. Employs the same correction methodology as in version 023. Updated code for OBC corrections leading to acquisition of data in IR wavelengths missed in previous versions. Version 023 - released 2 May 2017 - doi:10.5067/11ACLGMYOX89 Data availability: 2003/04/14 to 2018/05/21. Employs the same correction methodology as in version 022, but now includes a revision in the exposure time record bringing the exposure up-to-date rather than extrapolating the exposure. Code re-instates the daily calculations of SIM A and SIM B exposure time. -
