Version 04 is the current release of this data product, and supercedes all previous versions. The TSIS SIM Level 3 Solar Spectral Irradiance (SSI) 12-Hour Means data product (TSIS_SSI_L3_12HR) uses measurements from the Spectal Irradiance Monitor (SIM) instrument, and averages them over a 12-hour period. TSIS-1 was launched on December 15, 2017 and mounted on the International Space Station (ISS) on December 30, 2017. Solar spectra are measured over the spectral range from 200 to 2400 nm at a spectral resolution ranging from 2 nm (<0.28 microns) to 45 nm (>0.4 microns). 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 0.2%. All of the data from this product are arranged into a single file in a tabular ASCII text format which can be easily read into a spreadsheet application. New data are appended to the file on a daily basis. 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 mission.
