Fig. 2.

Breakdown of the parts contributing to the uniform field in SM coordinates. The observed annual mean values of SM fields are presented as plus signs. The model estimate of the −ZSM component is drawn as thick curve. This is composed of a constant bias (dashed-dotted), an Est dependent component (thin line), and a solar cycle dependent component approximated by the F10.7 index delayed by 20 months (dashed).
