CM5 (1.0)

Comprehensive Model Number 5 of the near-Earth magnetic field

Model Description

CM5 is a member of a suite of "Comprehensive Models" (CMs) that describes the near-Earth magnetic field and has been developed by NASA/GSFC and the Danish Technical University. The concept behind the CMs is to parameterize all major near-Earth magnetic field sources (core, lithosphere, M2 tidal, magnetosphere, ionosphere, associated induced fields, and toroidal fields within satellite sampling shells) and subsequentally co-estimate these in order to achieve optimal field separation. CM5 is an empirical inverse model derived from pre-Swarm satellite data (CHAMP, Oersted, and SAC-C) and ground observatory data from August 2000 to January 2013.
