    • calcGeoMag

      private void calcGeoMag(double latitude, double longitude, double height, double year)
      Computes the declination (dec), inclination (dip), total intensity (TI) and grid variation (GV - polar regions only, referenced to grid north of polar stereographic projection) of the Earth's magnetic field in geodetic coordinates from the coefficients of the current official department of defense (DoD) spherical harmonic World Magnetic Model (WMM-2010). The WMM series of models is updated every 5 years on January 1st of those years which are divisible by 5 (i.e. 1980, 1985, 1990, etc.) by the Naval Oceanographic Office in cooperation with the British Geological Survey (BGS). The model is based on geomagnetic survey measurements from aircraft, satellite and geomagnetic observatories.

      Accuracy: In ocean areas at the Earth's surface over the entire 5 year life of a degree and order 12 spherical harmonic model such as WMM-95, the estimated RMS errors for the various magnetic components are: DEC - 0.5 degrees DIP - 0.5 degrees TI - 200.0 nano Teslas (nT) GV - 0.5 Degrees

      Other magnetic components that can be derived from these four by simple trigonometric relations will have the following approximate errors over ocean areas: X - 140 nT (North) Y - 140 nT (East) Z - 200 nT (Vertical) Positive is down H - 200 nT (Horizontal)

      Over land the RMS errors are expected to be somewhat higher, although the RMS errors for DEC, DIP and GV are still estimated to be less than 0.5 degree, for the entire 5-year life of the model at the Earth's surface. The other component errors over land are more difficult to estimate and so are not given.

      The accuracy at any given time of all four geomagnetic parameters depends on the geomagnetic latitude. The errors are least at the equator and greatest at the magnetic poles.

      It is very important to note that a degree and order 12 model, such as WMM-2010 describes only the long wavelength spatial magnetic fluctuations due to Earth's core. Not included in the WMM series models are intermediate and short wavelength spatial fluctuations of the geomagnetic field which originate in the Earth's mantle and crust. Consequently, isolated angular errors at various positions on the surface (primarily over land, in continental margins and over oceanic seamounts, ridges and trenches) of several degrees may be expected. Also not included in the model are nonsecular temporal fluctuations of the geomagnetic field of magneto-spheric and ionospheric origin. During magnetic storms, temporal fluctuations can cause substantial deviations of the geomagnetic field from model values. In arctic and antarctic regions, as well as in equatorial regions, deviations from model values are both frequent and persistent.

      If the required declination accuracy is more stringent than the WMM series of models provide, then the user is advised to request special (regional or local) surveys be performed and models prepared by the USGS, which operates the US geomagnetic observatories.

      Parameters:
      latitude - the latitude in decimal degrees.
      longitude - the longitude in decimal degrees.
      height - the height (altitude) in kilometers.
      year - the date as a decimal year.
