The calculated result is a grid that contains the calculated component and the annual change of the component over the geographical area specified. WDeclination 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. 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. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. information pointOfContact NOAA National Centers for Environmental Information NCEI Geomagnetic Modeling Team geomag.models@noaa.gov pointOfContact asNeeded Earth Science > Solid Earth > Geomagnetism > Magnetic Field Earth Science > Solid Earth > Geomagnetism > Magnetic Intensity Earth Science > Solid Earth > Geomagnetism > Magnetic Declination Earth Science > Solid Earth > Geomagnetism > Magnetic Inclination theme Global Change Master Directory (GCMD) Science Keywords 2024 revision 19 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2024.

NCEI launched publicly on April 22, 2015. 2015-04-22T00:00:00 service User input of area of interest and time for desired data grid into a web interface. User data is sent via HTTP request to a java servelet hosted on a local NGDC server. This checks that all of the necessary information to run the model executable correctly is present and in the correct format. NGDC server accesses a C executable, in this case the IGRF executable, and inputs the user data and runs the executable to obtain desired output parameters in XML format. Processing steps were carried out collectively by the developers of the model. These developers are listed as authors of the associated paper "International Geomagnetic Reference Field: the eleventh generation". IGRF11 Spherical Harmonic Model. 2010-10-12 publication https://www.ngdc.noaa.gov/IAGA/vmod/igrf.html Refer to technical report, "International Geomagnetic Reference Field: the eleventh generation", for description of algorithms. The XML created by the executable is sent back to NGDC server and input into the Java servelet which reformats the output into the format designated by the user at the begining of the process. This reformatted information is returned to the User's webpage. The IGRF is the product of a collaborative effort between magnetic field modellers and the institutes involved in collecting and disseminating magnetic field data from satellites and from observatories and surveys around the world. The IGRF is a series of mathematical models of the Earth's main field and its annual rate of change (secular variation).
