The new operational World Magnetic Model (WMM2015) is released on NOAA's National Geophysical Data Center (NGDC) website. We also updated our online calculators to WMM2015 with several new features. The new model is valid from 2014-12-15 to 2019-12-31. The new WMM coefficient file (WMM.cof) has the same format as the previous file and is compatible with existing WMM software.
This message is to alert you that a new release of the WMM is available for download today!
