Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) / Solar EUV Experiment (SEE) Solar Emission Line Irradiance - Daily Average

The TIMED/SEE has been providing solar spectral irradiance measurements since Feb 8, 2002. The SEE Level 3 data products contain measured solar irradiances and 38 extracted emission lines ranging from 28.4 nm to 181.7 nm. The lines are integrated from higher spectral resolution data and the background is subtracted. Line irradiances represent a daily average. The measurements are adjusted to remove the 1-AU annual distance variation and median filtered to remove large flares prior to averaging. For higher cadence emission lines, including flares, refer to the SEE Level 3A data products.

We recommend using the SORCE SOLSTICE measurements when available for wavelengths longer than 115 nm. Since May 2010, SDO/EVE has been providing higher resolution, higher cadence spectra from 6-37 nm, and daily spectra from 6-65 nm.
