This Coordinated Data Analysis Workshop (CDAW) is
to bring together
scientists of Living With a Star (LWS) disciplines to interact and
establish long-term collaborations that can effectively address
questions related to CMEs, ICMEs, and their connections to geomagnetic
and ionospheric storms. The focal point of the CDAW will be the set of
all major geomagnetic storms of cycle 23 (79 events from 1996 to 2004).
Our
intent is
to attract participants who can contribute data, data
products, models, and analysis tools to achieve the scientific goals
of the CDAW. This would involve assembling and pre-processing the data
sets well ahead of the CDAW and a lot of effort has to go in much
before the workshop. The data from the CDAW and the results produced
during the CDAW will be made available on line after the workshop to
the broader scientific and space weather community for continued
research.
Possible
Scientific Questions:
--------------------------------------------------------------------------------------------
- What are the primary characteristics that make a CME
geoeffective?
- Can we infer the magnetic field structure (Bz south) from
the photospheric magnetograms?
- What is the relationship between solar filaments and the
ICME flux ropes?
- How do ICMEs affect the ring current and radiation belts?
- How is the total electron content (TEC) affected by the
ionospheric storms?
- What types of ICMEs are most geoeffective?
- What is the best way to predict the intensity of
geomagnetic storms?
- Why do some storms have no associated CMEs?
- Why don't some Earth-directed CMEs cause storms?
- What is the missing physics in MHD models and where
do they need improvement?
