SM 3D Location

Class Name: SM 3D Location

Superclass - <Location 3D>

Subclasses

This DRM class is concrete and has no subclasses.

Definition

An instance of this DRM class specifies a coordinate within the Solar Magnetic (SM) 3D SRF.

See [ISO/IEC 18026] for a complete definition.

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 SRM for additional details.
