Added ResourceType and NamingAuthority. Updated to 2.7.1. ZCB The EUV flux data came from the Extreme UltraViolet Spectrometer on the Atmosphere Explorer E. The data for 15 wavelength groups are normalized to the reference spectrum SC21REFW.DAT (located in directory REF_SPEC). GET_EUVS.FOR is a program to read the EUV data file (written by Dean Pesnell). The EUVS instrument is described in an article by Hinteregger in Radio Science, Volume 8, Number 4, 349-360, 1973. For more references please consult the file REF_LIST in the AEDOC directory. In addition to the solar EUV measurements, the EUVS also provided an opportunity to study the optical depth (absorption) of the thermosphere. Details of this analysis are described in: L.M. Chaikin and K. Fukui, Absorption Data Analysis for EUVS Experiment on the Satellites AE-C, D, and E, Air Force Geophysics Laboratory, Report AFGL-TR-79-0191, Hanscom AFB, Massachusetts, August 1979. spase://SMWG/Person/Dieter.K.Bilitza GeneralContact spase://VSPO/NumericalData/P_AE-E_HDR_EUV spase://VSPO/NumericalData/AE-E/EUVS/PT256S spase://SMWG/Repository/NASA/GSFC/SPDF Online Open https://spdx.org/licenses/ SPDX CC0-1.0 https://spdx.org/licenses/CC0-1.0.html Creative Commons Zero v1.0 Universal CC0 1.0 Universal is the Creative Commons license applicable to all publicly available NASA Heliophysics data products FTPBrowser https://omniweb.gsfc.nasa.gov/ftpbrowser/ae_e.html FTPS from SPDF (not with most browsers) ftps://spdf.gsfc.nasa.gov/pub/data/ae/ae_e/solar_euv_spectrophotometer/ae_e_euv_flux/ HTTPS from SPDF https://spdf.gsfc.nasa.gov/pub/data/ae/ae_e/solar_euv_spectrophotometer/ae_e_euv_flux/ In CDF via HTTP from SPDF Text CALIBRATED spase://SMWG/Instrument/AE-E/EUVS Radiance 1977-07-01T00:00:00 1981-06-09T23:59:59 PT256S Earth.NearSurface.Ionosphere Earth.NearSurface.Atmosphere
