SORCE XPS Level 4 Solar Spectral Irradiance 0.1nm Res 5-Minute V012 (SOR4XPS5) at GES DISC
The SORCE XPS Level 4 Solar Spectral Irradiance 0.1nm Res 5-Minute product (SOR4XPS5) contains modelled spectral extreme ultraviolet (XUV) irradiances based on calibrated SORCE XUV Photometer System (XPS) data and flare plasma temperature derived from the GOES XRS instrument. 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 nmERR_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 observationXPS_QS: Daily quiet-sun scale factor derived from XPS-1,-2 daily minimumXPS_AR: Daily active-region scale factor derived from XPS-1,-2 daily minimumXPS_FLARE: Flare scale factor for each XPS-1,-2GOES_QS: Daily quiet-sun scale factor derived from GOES XRS-B daily minimumGOES_AR: Daily active-region scale factor derived from GOES XRS-B daily minimumGOES_FLARE: Flare scale factor for each GOES XRS-B integrationFMTEMP: Flare model temperature [log10(K)] derived from ratio of GOES XRS-B to XRS-AFMINDEX: Index into flare model tableFMWEIGHT: Weight parameter for the flare model
