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. 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 DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce NCEI Geomagnetic Modeling Team geomag.models@noaa.gov http://www.ngdc.noaa.gov/geomag/ pointOfContact asNeeded http://www.ngdc.noaa.gov/geomag/img/DeclinationMap_US.png Magnetic Declination map for North America for the year 2010 PNG EARTH SCIENCE > Solid Earth > Geomagnetism > Magnetic Field EARTH SCIENCE > Solid Earth > Geomagnetism > Magnetic Declination theme NASA/GCMD Science Keywords NASA GCMD User Support Office gcmduso@gcmd.gsfc.nasa.gov http://gcmd.nasa.gov/MailComments/MailComments.jsf?rcpt=gcmduso GCMD Feedback Form Have a Comment for the GCMD? information custodian http://gcmd.nasa.gov/learn/keyword_list.html GCMD Keywords Page This page describes the NASA GCMD Keywords, how to reference those keywords and provides download instructions. information custodian Geographic Region > Global place NASA/GCMD Location Keywords NASA GCMD User Support Office gcmduso@gcmd.gsfc.nasa.gov http://gcmd.nasa.gov/MailComments/MailComments.jsf?rcpt=gcmduso GCMD Feedback Form Have a Comment for the GCMD? information custodian http://gcmd.nasa.gov/learn/keyword_list.html GCMD Keywords Page This page describes the NASA GCMD Keywords, how to reference those keywords and provides download instructions. information custodian DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce dataCenter NASA/GCMD Data Center Keywords NASA GCMD User Support Office gcmduso@gcmd.gsfc.nasa.gov http://gcmd.nasa.gov/MailComments/MailComments.jsf?rcpt=gcmduso GCMD Feedback Form Have a Comment for the GCMD? information custodian http://gcmd.nasa.gov/learn/keyword_list.html GCMD Keywords Page This page describes the NASA GCMD Keywords, how to reference those keywords and provides download instructions. information custodian While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state of the art, NOAA cannot assume liability for any damages caused by any errors or omissions in the data, nor as a result of the failure of the data to function on a particular system.

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 http://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).
