We describe here a model of the magnetic field created specifically to be used with data from the Champ satellite, valid for the initial period of the Champ mission (July 2000 — December 2001). The model contains initial field, linear secular variation and external field contributions. Although Champ data provide the most important input to the modelling, we also use data from other satellites (Ørsted and Ørsted-2/SAC-C) and ground-based observatories, to increase the robustness of the model. The model will be improved upon in the future (in particular as we better understand the local time dependencies of the external and induced magnetic fields) but for now is the recommended standard model for use with applications of Champ data.
