The higher resolution of the EMM results in significantly improved pointing accuracy than the World Magnetic Model (WMM), which uses spherical harmonic representation to degree and order 12, resolving the magnetic field at 3000 km wavelength. The EMM model provides the magnetic field vector at any desired location and altitude close to and above the Earth's surface. Magnetic anomaly maps provide insight into the subsurface structure and composition of the Earth's crust. Over continental areas, magnetic anomalies illuminate geologic, tectonic, and geothermal evolution of crust and lithosphere. In the world's oceans, anomalies trending parallel to the isochrons (lines of equal age) reveal the temporal evolution of oceanic crust. Magnetic maps are widely used in the geological sciences and in resource exploration. 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/EMM/img/dec_WMM_EMM.jpg Declination Comparison of WMM and EMM JPG 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 EARTH SCIENCE > Solid Earth > Geomagnetism > Magnetic Anomalies 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 otherRestrictions Cite as: National Geophysical Data Center (2009): Enhanced Magnetic Model 2010.

NCEI launched publicly on April 22, 2015. 2015-04-22T00:00:00 dataset Measurements during daytime and during periods of strong solar activity are contaminated by external current systems, which are difficult to accurately model. Therefore, only nighttime data during magnetically quiet periods were used in estimating the WMM coefficients.

Some contributions to the measured magnetic field, such as the diamagnetic effect of ionospheric plasma (L?hr et al, 2003) or motional induction by tidal ocean currents (Kuvshinov and Olsen, 2005; Maus, 2007), can be accurately modeled and were corrected for prior to the estimation of the WMM main field coefficients.

To account for the contributions that have not been removed in the previous steps, an extended set of model parameters is co-estimated with the WMM model coefficients. These account for smaller-wavelength internal magnetic field contributions (spherical harmonic degree larger than 12), second time derivatives (secular acceleration) and contributions from currents external to the Earth. The set of WMM coefficients plus the extended model parameters is called a parent model of the WMM. Two different parent models were produced, reflecting different modeling strategies employed by NGDC for the main field model and BGS for the secular variation model.

Satellite, marine, and aeromagnetic measurements were compiled into an ellipsoidal degree-720 magnetic model of the Earth's lithosphere. This model accurately represents the crustal field down to wavelengths of approximately 56 kilometers. This results in a higher pointing accuracy.
