SME 3D Location

Class Name: SME 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 Ecliptic SRFT.

See 8.5.14 Solar magnetic ecliptic SRFT of ISO/IEC 18026 for a complete definition.

Primary Page in DRM Diagram:

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 Ecliptic SRFT is convenient for representing such data as:
    1. magnetopause and shock boundary positions,
    2. magnetosheath and magnetotail fields, and
    3. magnetosheath solar wind velocities (since the orientation of the magnetic dipole axis alters the otherwise cylindrical symmetry of the solar wind flow).

FAQs

What kind of data is ordinarily represented in SME?

SME is quasi-inertial in that it rocks about the solar direction on both yearly (23.4 degrees +- 11.2 degrees) and 24 hour (+- 11.2 degree) cycles.
