This archive of GOES EUV data contains the raw 10-sec data and flags in daily ASCII text files 
for the EUVA, EUVB, and EUVE channels on the GOES 13, 14, and 15 satellites.  
 
The original data are on http://satdat.ngdc.noaa.gov/sem/goes/data/euvs/raw_10s/ in yearly files 
(separate data and flags files) and are described here: 

    http://www.ngdc.noaa.gov/stp/satellite/goes/doc/GOES_NOP_EUV_readme.pdf

The daily files in this archive were written by the SSW routine geuv_write_daily_files.pro. 
Geuv_write_daily_files.pro combines the data and flag data as well as possible, but if the 
flags or data are missing for a period, that period is not written at all in the daily output 
files.  Also, if the counts data from the original yearly file has <5 unique values for a given 
day, that daily file is not written.

The GOES object (and GOES workbench, a graphical interface to the GOES object) makes it easy to 
select time interval, satellite, and channel and plot these data, either as is or 
cleaned (filters out data during calibrations, eclipses, offpointing, etc).  Just type
  goes
in SSWIDL to start the GOES workbench. For remote users, the software finds the requested data 
on hesperia and copies the required files to their computer before plotting. The GOES object 
and workbench are described here:

Modifications:
06-Dec-2016  Rewrote this archive because NOAA made some changes:  
  NOAA data location is different (previously was 
  http://satdat.ngdc.noaa.gov/sem/goes/data/new_avg/yyyy/new_euv_temp/raw/),
  data now go up to June 2016 (previously Oct 2014), flags for euve data were improved, and euve data
  are now scaled by fit to SORCE SOLSTICE v15 Lyman-alpha (previously v13) to correct for degradation in
  the E channel (this last is done in the software reader, not in the data files themselves).
