  "Description": "Calculate magnetic field at a given location and time\naccording to the World Magnetic Model (WMM). Both the main\nfield and secular variation components are returned. This\nfunctionality is useful for physicists and geophysicists who\nneed orthogonal components from WMM. Currently, this package\nsupports annualized time inputs between 2000-01-01 to\n2029-12-31. If desired, users can specify which WMM version to\nuse, e.g., the original WMM2015 release or the recent\nout-of-cycle WMM2015 release. Methods used to implement WMM,\nincluding the Gauss coefficients for each release, are\ndescribed in the following publications: NOAA NCEI Geomagnetic\nModeling Team and British Geological Survey (2024)\n<doi:10.25921/aqfd-sd83>, Chulliat et al (2020)\n<doi:10.25923/ytk1-yx35>, Chulliat et al (2019)\n<doi:10.25921/xhr3-0t19>, Chulliat et al (2015)\n<doi:10.7289/V5TB14V7>, Maus et al (2010)\n<https://www.ngdc.noaa.gov/geomag/WMM/data/WMMReports/WMM2010_Report.pdf>,\nMcLean et al (2004)\n<https://www.ngdc.noaa.gov/geomag/WMM/data/WMMReports/TRWMM_2005.pdf>,\nand Macmillian et al (2000)\n<https://www.ngdc.noaa.gov/geomag/WMM/data/WMMReports/wmm2000.pdf>.",
