NOAA Space Environment Monitor (SEM) Science-Quality Extreme Ultraviolet (EUVS) Data from GOES 13 - 15

The Space Environment Monitor (SEM) Extreme Ultraviolet Sensor (EUVS) onboard the GOES satellite series measure the EUV in 5 GOES wavelength bands (A-E) from about 5-127 nm. This data is used to investigate solar activity and the associated impacts of extreme and middle ultraviolet absorption on the earth's atmosphere. This data collection includes Reprocessed Level-1b and Level-2 SEM/EUVS
data from GOES 13-15, channels A-E. The data are enhanced to science quality from the original operational archive. Enhancements include corrected calibrations, updated quality flagging, full ephemeris information, and both high-cadence and averaged data. The data were produced by NOAA’s National Centers for Environmental Information (NCEI) and archived by NOAA's Comprehensive Large Array-Data Stewardship System (CLASS).
