SORCE XPS Level 4 Solar Spectral Irradiance 0.1nm Res 5-Minute V012 (SOR4XPS5)

The model data are reported in the spectral range from 0-40 nm at a resolution of 0.1 nm about every 5 minutes. The XPS Level 2 data products, along with CHIANTI reference spectra, are used to construct the XPS Level 4 data products.

The SOR4XPS5 data are stored in netCDF files containing one year of data. Data variables stored in each file include: MODELFLUX: Array of solar irradiances [W/m2/nm] in 0.1 nm bins from 0.1 to 39.9 nm ERR_ABS: Total combined standard uncertainty of the model flux irradiance results (accuracy) ERR_MEAS: Count-rate based combined standard uncertainty of the XPS-1,-2 measurement (precision) DATE: Year and day-of-year of observation (YYDDD) TIME: Seconds of day for middle of observation XPS_QS: Daily quiet-sun scale factor derived from XPS-1,-2 daily minimum XPS_AR: Daily active-region scale factor derived from XPS-1,-2 daily minimum XPS_FLARE: Flare scale factor for each XPS-1,-2 GOES_QS: Daily quiet-sun scale factor derived from GOES XRS-B daily minimum GOES_AR: Daily active-region scale factor derived from GOES XRS-B daily minimum GOES_FLARE: Flare scale factor for each GOES XRS-B integration FMTEMP: Flare model temperature [log10(K)] derived from ratio of GOES XRS-B to XRS-A FMINDEX: Index into flare model table FMWEIGHT: Weight parameter for the flare model
