Geomagnetic elements

Term · Meteorology and atmospheric science · MLC-T-MET-001140

In solar-terrestrial terms, the components of the geomagnetic field at the surface of the earth. In SESC use, the northward and eastward components are often called the H and D components, where the D component is expressed in gammas and is derived from D (the declination angle) using the small angle approximation.
