2.2.2 spase://VITMO/NumericalData/TIMED/SEE/L2_XPS TIMED SEE Level2 XPS Solar Irradiance Data 2011-10-21T12:00:00.000 The 12 X-Ray Photometers (XP) aboard SEE perform full-disk irradiance measurements of the Sun for about 3 minutes every orbit (97 minutes) which usually gives 14-15 measurements per day. 8 of the XPs produce XUV signals (more info on XP coatings) and one other XP provides a hydrogen Lyman-alpha measurement (121.5 nm). The XPS Level 2 data is time averaged over the entire day, after being 1-AU corrected and removing flares. The 1-AU correction is provided. NASA, Thomas N.
