A full description of the indices Kn, Ks, Km is given in a monography,"Indices Kn, Ks et Km, 1964-1967", edited in 1968 by the Centre National de la Recherche Scientifique, 15 quai Anatole, France, 75007 Paris, which contains these indices for 2964-1967 while the International Association of Geomagnetism and Aeronony (IAGA) Bulletin NO. 39 contains those for 1959-1963. 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.

NOAA National Centers for Environmental Information
NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
