2.2.2 spase://NASA/NumericalData/TIMED/SEE/L2A_EGS TIMED SEE Level2A EGS Solar Irradiance Data 2020-07-07T21:15:38Z 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 2A data is time averaged over each measurement, after being 1-AU corrected and removing flares. The 1-AU correction is provided. NASA, Thomas N.
