The National Geospatial-Intelligence Agency (NGA) highly recommends that all DoD systems use the WMMHR instead of the WMM. 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 Associated WMMHR2025 software may be updated as improvements are created. https://www.ngdc.noaa.gov/geomag/WMM/icons/WMMHR2025/WMMHR2025_D_BoZ_MILL.png Declination contour map in miller projection PNG 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.
