AS PART OF THE REGULAR UPDATE CYCLE OF THE\n WORLD MAGNETIC MODEL (WMM),\n THE NATIONAL OCEANOGRAPHIC & ATMOSPHERIC\n ADMINISTRATION (NOAA)/ NATIONAL CENTERS\n FOR ENVIRONMENTAL INFORMATION (NCEI), IN\n COLLABORATION WITH THE BRITISH GEOLOGICAL\n SURVEY (BGS), WILL RELEASE THE WMM2025\n ON 17 DEC 24. THE CURRENT 2020 WMM\n WILL EXPIRE ON 31 DEC 24. \n2. IN ORDER TO AVOID ANY MODEL PERFORMANCE\n DEGRADATION, USERS ARE RECOMMENDED TO\n DOWNLOAD AND INSTALL THE WMM2025 MODEL\n COEFFICIENTS, WHICH WILL BE PUBLISHED ONLINE\n AT HTTPS://WWW.NCEI.NOAA.GOV/PRODUCTS/\n WORLD-MAGNETIC-MODEL.\n3. THE WMM IS THE STANDARD MODEL USED BY\n THE U.S. DEPARTMENT OF DEFENSE (DOD),\n CIVIL AGENCIES, THE NORTH ATLANTIC TREATY\n ORGANIZATION (NATO), AND THE INTERNATIONAL\n HYDROGRAPHIC ORGANIZATION, OR A\n WIDE-RANGE OF POSITIONING AND NAVIGATION\n SYSEM APPLICATIONS THAT USE THE\n GEOMAGNETIC FIELD, INCLUDING ALL AIRCRAFT,\n SHIPS, SUBMARINES, AND GPS UNITS.\n4. FOR SOME USERS THAT HAVE REQUESTED A WMM\n WITH PERFORMANCE THAT EXCEEDS MILITARY\n REQUIREMENTS, NGA HAS ADDED AN ADVANCED\n WMMHR2025 (HIGH RESOLUTION) TO THIS WMM\n RELEASE CYCLE. WMMHR2025 IS FOR THOSE SYSTEMS\n THAT CAN ACCEPT ADDITIONAL MODEL COEFFICIENTS\n BEYOND THOSE PROVIDED IN ALL PRIOR WMM RELEASES.\n NGA ENCOURAGES, BUT DOES NOT REQUIRE,\n USERS TO UPDATE THEIR SYSTEMS WITH\n WMMHR2025 WHEN THIS IS RELEASED. FOR TEST\n PURPOSES, A BETA VERSION (WMMHR2020)\n CAN BE DOWNLOADED FROM THE NOAA AND\n NGA WMM OPENSOURCE WEBSITES BEGINNING 9/1/2024. \n SEE HTTPS://WWW.NGDC.NOAA.GOV/GEOMAG/\n DATA/WMM/WMMHR/ FOR A COMPLETE DESCRIPTION. \n NGA REQUESTS USERS PROVIDE FEEDBACK ON\n BETA PERFORMANCE TO NOAA \n EMAIL:GEOMAG.MODELS@NOAA.GOV. \n5.
