SE-51, Bibliography of Historical Geomagnetic Main Field Survey and Secular Variation Reports at the World Data Center-A for Solid Earth Geophysics. abstract: Information on the past and present orientation of the Earth's magnetic field is available from the National Geophysical Data Center (NGDC) which serves as the national data bank for geomagnetic data. The Earth's magnetic field has been measured by land surveys, ships, aircraft and satellites at hundreds of locations resulting in millions of observations. Many of the observations are of poor quality or are unevenly distributed around the globe. Because of these limiting factors and the variation of the main magnetic field with time, the Earth's field is usually approximated by mathematical models. These models, adjusted to fit selected available observations, have wide application in geophysical and space sciences. Surveyors can obtain data and information for individual specific locations worldwide. Past values of the magnetic field are available from models for areas within the conterminous U.S. from 1750 or from 1945 worldwide. These mathematical models must be periodically updated due to the changing nature of the Earth's magnetic field. NGDC maintains the models and data base of observations to track secular variation of the Earth's magnetic field. Models and software are available on-line. The global geomagnetic observations data bases for secular change studies include high-quality magnetic observations made at observatories worldwide since 1800. Other geomagnetic data bases are: IAGA Repeat Station data base which contains observations from exact reoccupations, Other land Surveys containing miscellaneous land observations worldwide since 1800 including a few thousand observations made at sea by the non-magnetic ships, Carnegie and Zarya, Vector airborne surveys from the Project Magnetic aircraft, satellite and selected marine observations. Most of the surface data are available on-line. At most locations, three magnetic elements were observed: Either declination (D), Inclination (I), and horizontal intensity (H), or declination, horizontal intensity, and vertical intensity (Z), or total intensity (F). Where possible, the values for other magnetic elements, usually the north component (X) and east component (Y), were derived by the computer. The altitude, latitude, and longitude are recorded for each observation. The observatory annual means file contains the results of more of the observatories operating since 1800. Files are revised as new data become available. Searches and plots of data from selected stations can be made. These secular change files are the principal source for tracking the long-period changes in the direction and intensity of the Earth's magnetic field. Other data include a digital bibliography of historical magnetic survey publications at NGDC and the co-located World Data Center-A. Over 750 reports published from the 1830's to 1980's were inventoried in a digital bibliography and digitally imaged in .PCX format. The digital images of these reports have been written to magnetic tape. purpose: Provide information for research and surveyors status: (MD_ProgressCode) underDevelopment pointOfContact: (CI_ResponsibleParty) individualName: Brian Meyer organisationName: NOAA National Centers for Environmental Information contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 303-497-6125 address: (CI_Address) electronicMailAddress: Brian.Meyer@noaa.gov role: (CI_RoleCode) pointOfContact resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) annually descriptiveKeywords: (MD_Keywords) keyword: EARTH SCIENCE>SOLID EARTH>Geomagnetism>Geomagnetic Forecasts keyword: EARTH SCIENCE>SOLID EARTH>Geomagnetism>Geomagnetic Indices keyword: EARTH SCIENCE>SOLID EARTH>Geomagnetism>Geomagnetic Induction keyword: EARTH SCIENCE>SOLID EARTH>Geomagnetism>Magnetic Anomalies keyword: EARTH SCIENCE>SOLID EARTH>Geomagnetism>Magnetic Declination keyword: EARTH SCIENCE>SOLID EARTH>Geomagnetism>Magnetic Inclination keyword: EARTH SCIENCE>SOLID EARTH>Geomagnetism>Magnetic Intensity keyword: EARTH SCIENCE>SOLID EARTH>Geomagnetism>Paleomagnetism keyword: EARTH SCIENCE>SOLID EARTH>Geomagnetism>Reference Fields type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Science 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.
