2.2.2 spase://VSPO/NumericalData/Alouette2/SFS/Ionograms Alouette 2 Topside Sounder Ionogram Over Multiple Stations 2012-04-11T10:42:30 This data set consists of ionograms derived from Alouette 2 Sweep-Frequency Sounder measurements for the ionosphere above the F2 maximum (topside ionosphere). These ionograms are reduced data plots showing as a function of fixed and swept frequency the echo time delay (virtual range) of pulsed radio signals at 355 virtual heights. They were converted from the original analog telemetry tapes covering various stations: Winkfield, U.K. (lat/lon=51/359); Quito, Ecuador (lat/lon=-1/281); Lima, Peru (Lat=-12, Long=283); Santiago, Chile (lat/lon=-33/298); and Falkland Is., U.K. (lat/lon=-52/302). spase://SMWG/Person/Robert.F.Benson GeneralContact spase://VSPO/NumericalData/P_Alouette2_HDR_Multi_Station_Topside_Sounder_Ionograms spase://SMWG/Repository/NASA/GSFC/SPDF/CDAWeb Online Open Winkfield data from SPDF FTP area ftp://spdf.gsfc.nasa.gov/pub/data/alouette/topside_sounder/ionogram_cdaweb/alouette2/WNK_51N_359E/ Winkfield data from SPDF HTTP area http://spdf.gsfc.nasa.gov/pub/data/alouette/topside_sounder/ionogram_cdaweb/alouette2/WNK_51N_359E/ In CDF via HTTP from CDAWeb CDAWeb http://cdaweb.gsfc.nasa.gov ALOUETTE2_AV_WNK ALOUETTE2_AV_WNK Quito data from SPDF FTP area ftp://spdf.gsfc.nasa.gov/pub/data/alouette/topside_sounder/ionogram_cdaweb/alouette2/QUI_01S_281E/ Quito data from SPDF HTTP area http://spdf.gsfc.nasa.gov/pub/data/alouette/topside_sounder/ionogram_cdaweb/alouette2/QUI_01S_281E/ In CDF via HTTP from CDAWeb CDAWeb http://cdaweb.gsfc.nasa.gov ALOUETTE2_AV_WNK ALOUETTE2_AV_QUI Lima data from SPDF FTP area ftp://spdf.gsfc.nasa.gov/pub/data/alouette/topside_sounder/ionogram_cdaweb/alouette2/LIM_12S_283E/ Lima data from SPDF HTTP area http://spdf.gsfc.nasa.gov/pub/data/alouette/topside_sounder/ionogram_cdaweb/alouette2/LIM_12S_283E/ In CDF via HTTP from CDAWeb CDAWeb http://cdaweb.gsfc.nasa.gov ALOUETTE2_AV_WNK ALOUETTE2_AV_LIM Santiago data from SPDF FTP area ftp://spdf.gsfc.nasa.gov/pub/data/alouette/topside_sounder/ionogram_cdaweb/alouette2/SNT_33S_298E/ Santiago data from SPDF HTTP area http://spdf.gsfc.nasa.gov/pub/data/alouette/topside_sounder/ionogram_cdaweb/alouette2/SNT_33S_298E/ In CDF via HTTP from CDAWeb CDAWeb http://cdaweb.gsfc.nasa.gov ALOUETTE2_AV_WNK ALOUETTE2_AV_SNT Falkland Island from SPDF FTP area ftp://spdf.gsfc.nasa.gov/pub/data/alouette/topside_sounder/ionogram_cdaweb/alouette2/SOL_52S_302E Falkland Island fromSPDF HTTP area http://spdf.gsfc.nasa.gov/pub/data/alouette/topside_sounder/ionogram_cdaweb/alouette2/SOL_52S_302E In CDF via HTTP from CDAWeb CDAWeb http://cdaweb.gsfc.nasa.gov ALOUETTE2_AV_WNK ALOUETTE2_AV_SOL CDF CALIBRATED spase://SMWG/Instrument/Alouette2/SFS ThermalPlasma 1965-11-29T13:42:37 1968-01-01T04:12:17 Earth.NearSurface.Ionosphere
