Solar EUV Experiment (SEE) Data from the Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics (TIMED) Mission
Listed in NASA Earthdata CMR
The Solar EUV Experiment (SEE) is one of four instruments that constitute the TIMED spacecraft, the first mission of the NASA Solar Connections program.
Description
All SEE data products contain daily averaged solar irradiance data with corrections applied for degradation, 1-AU, and atmospheric absorption. The SEE Level 2 data contains EGS and XPS solar irradiance data averaged over the entire day, after being 1-AU corrected and removing flares.
The EUV Grating Spectrograph (EGS) aboard SEE performs measurements of the Sun for about 3 minutes every orbit (97 minutes) which usually gives 14-15 measurements per day. The Level 2 data is time averaged over the entire day, after being 1-AU corrected and removing flares. The 1-AU correction is provided.

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 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.
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. Shortware 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.
