This class appears on only one page of the DRM class diagram.

Example

  1. SM provides a convenient spatial reference frame for ordering data controlled more strongly by the Earth's dipole field than by solar wind. It has been used for representing magnetopause cross-sections and magnetospheric magnetic fields.

FAQs

Is SM inertial?

SM is quasi-inertial in that it rotates with both a yearly and daily period.

Where can users obtain further information on SM?

See the Spatial Reference Model (SRM) for additional details.
