The data consist of virtual height/frequency pairs from a profile or profiles (composite months) of ionograms. Data includes the station, year, month and hour (or composite month) for each record. Data are available on 9-track magnetic tape. Electron density profiles are also available in Dataset_ID: G10145. The stations included are Argentia, Bermuda, College, Dyess, Goose Bay, Narssarssuaq, Puerto Rico, Sondestrom, Thule, and Wallops Island.Ionospheric Research1954121519931231UnknownCompletenotPlanned-180.000000180.00000090.000000-90.000000NASA/GCMD Earth Science KeywordsEARTH SCIENCE > Sun-earth Interactions > Ionosphere/Magnetosphere Particles > Particle DensityUncontrolled KeywordsN(h)GCMD Location ThesaurusGlobalRestriction Code: otherRestrictions; Use Limitation: While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state of the art, NOAA cannot assume liability for any damages caused by any errors or omissions in the data.; Other: Use Constraints: None; Other: Access Constraints: No Constraints; DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of CommerceJustin Mabiephysical and mailing NOAA/NESDIS/NGDC 325 Broadway BoulderCO80305(303) 497-6135ionosonde@noaa.govUnknown 20101021Justin MabieDOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commercemailing and physical 325 Broadway, Mail Code E/GC4 BoulderCO80305-3328(303) 497-6135Justin.Mabie@noaa.govContent Standard for Digital Geospatial Metadata: Extensions for Remote Sensing MetadataFGDC-STD-012-2002
