  • SORCE SOLSTICE Level 3 MgII Core-to-Wing Ratio As-Measured Cadence V018 (SOR3SOLS_MGII_018) at GES DISC

    https://cmr.earthdata.nasa.gov/search/concepts/C1993479669-GES_DISC.xml
    Description:

    The SORCE SOLSTICE Level 3 MgII Core to Wing Ratio As-Measured Cadence product consists of all measurements of the magnesium II core-to-wing index from the SOLSTICE instrument. The SOLSTICE instrument makes measurements during each daytime orbit portion, 15 orbits per day. A complete solar spectrum is made in about 30 minutes, a quick scan mode in about 5 minutes. The spectral resolution of SOLSTICE is 0.1 nm, allowing the Mg-II doublet to be fully resolved and modeled with Gaussians. The Mg-II core-to-wing ratio is used as a measurement of solar activity. The Mg-II 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), the core/wing ratio, and the absolute uncertainty. The rows are arranged with one daily average measurment, repeating for each day for the length of the measurement period.

  • SORCE SOLSTICE MUV Level 3 Solar Spectral Irradiance Daily Means V018 (SOR3SOLMUVD) at GES DISC

    https://cmr.earthdata.nasa.gov/search/concepts/C1991623701-GES_DISC.xml
    Description:

    Version 018 is the final version of this data product, and supersedes all previous versions. The SORCE SOLSTICE Mid-UV Solar Spectral Irradiance (SSI) data product SOR3SOLMUVD is constructed using measurements from the SOLSTICE MUV instrument, which are combined into merged daily solar spectra over the spectral range from 180 to 310 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 SOR3SOLMUVD 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.
