Spencer) during the AEROS-A satellite mission. The data are in ASCII format and cover the time period from 12/26/1972 to 8/9/1973. The four different files provided in this data set contain the data for He, O2, N2, and Ar, respectively. Each data record provides date, time, density, density error, altitude, latitude and longitude, and local solar time. spase://SMWG/Person/Dieter.K.Bilitza GeneralContact spase://VSPO/NumericalData/P_AEROS_HDR_Neutral_Gas spase://VSPO/NumericalData/Aeros-A/NATE/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/aeros.html FTPS from SPDF (not with most browsers) ftps://spdf.gsfc.nasa.gov/pub/data/aeros/aeros-a/neutral_gas/ AEROS-A_neutral_gas HTTPS from SPDF https://spdf.gsfc.nasa.gov/pub/data/aeros/aeros-a/neutral_gas/ In CDF via HTTP from SPDF Text CALIBRATED spase://SMWG/Instrument/Aeros-A/NATE NeutralGas 1972-12-26T00:00:00 1973-08-09T23:59:59 PT256S Earth.NearSurface.Ionosphere Earth.NearSurface.Atmosphere
