Each calculation is for a specific location, elevation and date or range of dates. The calculated result can be obtained from two separate geomagnetic models, the IGRF11 or the WMM2010. Declination is calculated using the current World Magnetic Model (WMM) or International Geomagnetic Reference Field (IGRF) model. While results are typically accurate to 30 minutes of arc, users should be aware that several environmental factors can cause disturbances in the magnetic field. purpose: The purpose of the calculators is to deliver trusted magnetic field values - past, present, and near future - to aid the public as well as the scientific community in proper navigation, positioning, and other operational and research magnetic field scenarios. status: (MD_ProgressCode) completed status: (MD_ProgressCode) historicalArchive pointOfContact: (CI_ResponsibleParty) organisationName: NOAA National Centers for Environmental Information contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: ncei.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://www.ncei.noaa.gov/contact name: NCEI Contact Information description: Information for contacts at NCEI. function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) pointOfContact pointOfContact: (CI_ResponsibleParty) organisationName: NOAA National Centers for Environmental Information positionName: NCEI Geomagnetic Modeling Team contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: geomag.models@noaa.gov role: (CI_RoleCode) pointOfContact resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) asNeeded descriptiveKeywords: (MD_Keywords) keyword: Earth Science > Solid Earth > Geomagnetism > Magnetic Field keyword: Earth Science > Solid Earth > Geomagnetism > Magnetic Intensity keyword: Earth Science > Solid Earth > Geomagnetism > Magnetic Declination keyword: Earth Science > Solid Earth > Geomagnetism > Magnetic Inclination 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.
