At its meeting in July 1999, the IAGA Working Group for Analysis of the Global and Regional Geomagnetic Field and Secular Variation (WG V-8) felt unable to decide on a main-field model to use for IGRF 2000. It therefore set up a small Task Force with the remit to produce a model by the end of the year. This paper is the Chairman’s report of the working of that Task Force, outlining the various stages involved, and giving the background to the various decisions. He also makes some retrospective personal comments.
