Magnetic Field Calculators

The new operational World Magnetic Model will be released on December 15th 2014. This release will include estimated uncertainties for each of the magnetic field elements. In addition to being able to download the new WMM, we will also update the web calculators with the new model. As we get closer to the release, we will post additional information about the calculator updates on the WMM home page. Please be assured, the WMM coefficient file format will not change with the update for 2015-2020.
