Abstract:
The present proposal concerns analysis of the archived (level-1, calibrated) set of full-disk magnetograms recorded by the SOI, with the aim of exploring the evolution of the global magnetic field pattern on the various time scales covered by the data set. Both the rotational properties of the pattern and the evolution in terms of the harmonic modal components will be analysed, to shed light on the interior sources of the field pattern and the nature of the solar dynamo. The program will be combined with a corresponding investigation with the GOLF circular polarization data set, which should allow the sources of the mean-field signal to be identified.
