Data Description:
WSA input: The inputs to the model are derived from the Mt. Wilson
Observatory Observatory solar magnetograms. The details of
transforming the raw individual magnetograms into a global, synoptic
characterization are given in Arge, C.N., and V.J. Pizzo, Improvement
in the prediction of solar wind conditions using near-real time solar
magnetic field updates, Journal of Geophysical Research, Volume 105,
Issue A5, May 1, 2000, pp.10465-10480, 2002.
Description of Model:
WSA Model: The WSA model currently produces real-time predictions of the solar wind at SEC/NOAA. Currently, we are using historical predictions of this model to drive various empirical models that require only the solar wind speed as an input.
The WSA is a modular Sun-to-Earth model that permits easy replacement
of individual modules by improved ones as they (and any required data
streams) become available.
The four modular components of the prototype Sun-Earth model consist
of simple physics-based and semi-empirical models as well as numerical
MHD models that can run on workstations. An advantage of the modular
architecture is that it allows for extensive experimentation and
permits easy replacement of individual models by improved ones as they
(and any required data streams) become available.
A recent talk given by Nick Arge at HAO gives an overview of the model. [.ppt]
