gov.noaa.ngdc.mgg.geophysical_models:EMM201020061101The Enhanced Magnetic Model (EMM) extends to degree and order 720, resolving magnetic anomalies down to 56 km wavelength. 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.2000010120141231UnknownCompleteasNeeded-18018090-90NASA/GCMD Science KeywordsEARTH SCIENCE > Solid Earth > Geomagnetism > Magnetic FieldEARTH SCIENCE > Solid Earth > Geomagnetism > Magnetic IntensityEARTH SCIENCE > Solid Earth > Geomagnetism > Magnetic DeclinationEARTH SCIENCE > Solid Earth > Geomagnetism > Magnetic InclinationEARTH SCIENCE > Solid Earth > Geomagnetism > Magnetic AnomaliesNASA/GCMD Location KeywordsGeographic Region > GlobalNoneUse Limitation: 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.
