Inversion methods capable of reliably probing the subsurface structure beneath regions of strong magnetic fields, such as sunspots, remain elusive. We will review progress of a SDO Science Center project, funded to (among other goals) develop and evaluate new methods for this problem. Progress to date has included extensive production of magneto-convective sunspot models for the testing and validation of existing methods, for which a 27 hour run of artificial photospheric Dopplergrams is available online to the community. We will also summarize progress on the use of magnetostatic models for the development and testing of novel inversion methods designed to distinguish between magnetic field and thermal perturbations.
This work is supported by NASA contracts NNH09CE41C and NNG07EI51C.
