\begin{abstract}
Solar wind models are highly dependent on global magnetic fields at the
solar surface as their inner boundary condition, and the lack of global
field data is a significant problem plaguing solar wind modeling.
Currently, only direct observations of the near-side magnetic field
exist and far-side approximations are incapable of predicting growth of
existing active regions or new magnetic flux emergence. To fill this
data gap, we develop a method that calibrates far-side helioseismic
images, which are calculated using near-side Doppler observations, to
far-side magnetic flux maps. The calibration employs multiple
machine-learning methods that use EUV 304 \selectlanguage{ngerman}Å data as a bridge. These
algorithms determine a relation 1) between the near-side AIA 304 Å data
and HMI magnetic field data, and 2) between STEREO 304 Å data and
far-side helioseismic images obtained from a newly developed
time-distance helioseismic far-side imaging method. The resulting
magnetic flux maps have been further calibrated using maps produced by a
flux transport model. The various data products from this work ---
far-side acoustic maps, far-side STEREO EUV-derived magnetic flux maps,
and near-real-time acoustically-driven far-side magnetic flux maps,
along with maps of the associated uncertainties --- are being made
available to enable a synchronic global magnetic flux input into coronal
and solar wind models.%
