Yearly computations of these data are published in the series of IAGA Bulletin No.32. All of them are available in digital form at the appropriate World Data Center. Briefly, the three-hourly indices Kn and Ks for the Northern and Southern Hemispheres respectively are derived from the K indices of observatories approximately well distributed in latitude and in longitude. The indices are standardized according to the distances of the stations to the auroral zones. The stations are arranged in groups representing a longitude sector in one of the hemispheres (5 in the Northern Hemisphere, 4 in the Southern). The observatories currently in use are: MGD-Magadan, EYR-Eyrewell, PET-Petropavlovsk, LAU-Lauder, MMB-Memambetsu, CAN-Canberra, POD-Podkammenaya Tunguska, SVE-Sverdlovsk, GNA-Gnangara, NGK-Niemegk, KGL-Kerguelen, CZT-Crozet, HAD-Hartland, HER-Hermanus, OTT-Ottawa, AIA-Argentine Island, FRD-Fredericksburg, NEW-Newport, VIC-Victoria, TUC-Tucson The mean standardized K of each sector is converted into an equivalent amplitude and the weighted (in longitude) averages and these amplitudes are converted back into Kn and Ks. Km is derived in the same way from am, the average of an and as. Indices an, as and am are expressed in gammas (one gamma equals one nanoTesla) and correspond to the magnetic activity level (as it can be inferred from K indices 0 at an invariant magnetic latitude of 50 degrees. Indices Kn, Ks and Km are expressed in the same units as Kp. Values published in these reports are only provisional because in some months all observatories used in each longitude sector have not sent K indices at the right time and because K indices of Antarctic Stations have be rescaled at the end of each wintering. purpose: Monitor Geomagnetic Activity status: (MD_ProgressCode) underDevelopment pointOfContact: (CI_ResponsibleParty) individualName: Justin Mabie organisationName: DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce positionName: Space and Terrestrial Weather Specialist contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (303) 497-6135 facsimile: (303) 497-6513 address: (CI_Address) deliveryPoint: 325 Broadway, Mail Code E/GC4 city: Boulder administrativeArea: CO postalCode: 80305-3328 country: USA electronicMailAddress: Justin.Mabie@noaa.gov role: (CI_RoleCode) pointOfContact resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) monthly descriptiveKeywords: (MD_Keywords) keyword: EARTH SCIENCE > SOLID EARTH > Geomagnetism > Geomagnetic Indices type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: NASA/GCMD Earth Science Keywords date: (unknown) descriptiveKeywords: (MD_Keywords) keyword: Ks, Kn, Km Indices keyword: Geomagnetic Field keyword: Azimuthal Component type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: Uncontrolled Keywords date: (unknown) descriptiveKeywords: (MD_Keywords) keyword: Global keyword: Magnetosphere type: (MD_KeywordTypeCode) place thesaurusName: (CI_Citation) title: NASA/GCMD Location Keywords date: (unknown) descriptiveKeywords: (MD_Keywords) keyword: DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce keyword: DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce type: (MD_KeywordTypeCode) dataCentre thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Data Center Keywords date: (CI_Date) date: 2020-01-09 dateType: (CI_DateTypeCode) publication edition: 9.1 citedResponsibleParty: (CI_ResponsibleParty) organisationName: NASA Goddard Space Flight Center, Earth Science Data and Information System contactInfo: (CI_Contact) onlineResource: (CI_OnlineResource) linkage: https://www.earthdata.nasa.gov/learn/find-data/idn/gcmd-keywords name: Global Change Master Directory (GCMD) Keywords description: The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.
