The magnetic field differences in reference to sea level height are negligeable. 2References for the magnetic field calculation portion (field direction … WebMagnetic declination is defined as the angle between magnetic north and true north on the horizontal plane, which is not constant and keeps changing depending upon the position on the earth’s surface and time. The Greek letter δ is used as the symbol for magnetic declination and is also known as magnetic variation.

WebGeomagnetic Inclination D (DEC): Geomagnetic Declination (Magnetic Variation) Input Parameters The input parameters and valid entries are: Latitude: -90.00 to +90.00 degrees Longitude: -180.00 to +180.00 degrees Altitude: -1 to 850km referenced to the WGS 84 ellipsoid OR the Mean Sea Level (MSL) Date: 2024.0 to 2025.0 WebDeclination is simply a manifestation of the complexity of the geomagnetic field. The field is not perfectly symmetrical; it has non-dipolar "ingredients," and the dipole itself is not perfectly aligned with the rotational axis of the Earth.
