Advancing the Advective Flux Transport Model
Abstract
The Advective Flux Transport (AFT) model has proven to be a reliable surface flux transport model for describing the evolution of the global magnetic field, accurately reproducing the evolution of the polar field. AFT has also been shown to accurately (within a factor of 2) reproduce the evolution of the total unsigned flux of simple active regions over the course of their lifetimes. Here we will discuss the work being done to validate and advance the AFT model. We will discuss the ability of AFT to reproduce other active region properties, such as tilt angles, polarity separation, area expansion and magnetic elements size distribution, for simple and more complex active regions. Currently, AFT uses data assimilation to incorporate the magnetic field from magnetograms from the Earth's vantage point. We will also discuss the work that is being done to develop an automated process for adding in far-side active regions observed by STEREO in 304 Å.
