Description
SEE Level 3 data files contain one daily averaged solar irradiance spectrum in 1 nm intervals extracted from the EGS Level 2 and XPS Level 2 data products. Shortward of 27 nm, a solar model is scaled to match the XPS broadband data. SEE Level 3 data files also contain 38 emission lines extracted from EGS Level 2 spectra, and the XPS Level 2 diode irradiances.
For normal operations, SEE observes the Sun for about 3 minutes every orbit (97 minutes), which usually gives 14-15 measurements per day. The SEE Level 3 data are time averaged over the entire day, after applying corrections for atmospheric absorption, degradation, flare removal, and to 1-AU.

Description
Merged Solar irradiance for XPS and EGS flux at 1nm bins with gaps filled using Woods-Rottman 2002 VUV model. Below 26 nm, flux is result of solution of linear equations involving XPS diodes and scaled to the VUV model. EGS data is used above 26 nm except 114.5-120.5 and 122.5-128.5 nm where the VUV model is scaled to the EGS Lyman-alpha line.
