SMD 3D Location

Class Name: SMD 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 for an SRF based on the Solar Magnetic Dipole SRFT.

See 8.5.15 Solar magnetic dipole SRFT of ISO/IEC 18026 for a complete definition.

Secondary Pages in DRM Diagram:

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

Example

  1. An SRF derived from the Solar Magnetic Dipole SRFT is convenient for ordering data controlled more strongly by the dipole field of the Earth than by solar wind. It is used for representing magnetopause cross-sections and magnetospheric magnetic fields.

FAQs

Is SMD inertial?

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

Where can users obtain further information on SMD?

See the SRM for additional details.
