Welcome to the Coordinated Data Analysis Workshop
The CDAW Concept
The Coordinated Data Analysis Workshop (CDAW) program is
sponsored by the Space Physics Data Facility and is
an effort to further the development and use of tools and techniques implementing
large simultaneous data from many investigators, for selected event periods,
the program aims to address problems of global scale that may not be
The operating CDAW program is distinguished by its
combination of a traditional workshop format with assembly
of a digital data base where the data and relevant models
have been cast into a common format.

The CDAW Data Bases
Since the first CDAW, in December 1977, nine coordinated
databases (CDBs) have been assembled. The ninth (CDB9)
became public in December, 1993. The CDB's contain data for the
specific CDAW event time periods, which are typically 16 hours or
less.The CDBs 6 through 9 are accessible on-line and are
- CDAW-9: five events from the period April-May 1986
during the PROMIS (Polar Regions Outer Magnetosphere
International Study) observational campaign period,
including conjugate auroral imaging data from both DE-1 and
Viking. During the PROMIS period, an international effort
was made to gather simultaneous solar-terrestrial
observations toward the goal of an improved understanding of
the relation between polar phenomena and physical processes
in the magnetosphere as a whole.
- CDAW-8: eight events from the period January-June 1983,
during the time when ISEE-3 was transiting the deep
magnetotail, with one focus a search for "plasmoid"
signatures and including DE-1 auroral imaging data;
- CDAW-7: two events from the period April-May 1979,
selected to facilitate comparison of specific differing
models of magnetospheric substorms;
- CDAW-6: two events from March 1979, selected as unique
combinations of interesting magnetospheric phenomena and
simultaneous coverage by existing spacecraft and ground
- The CDBs from 1 through 5 are no longer accessible as
databases, although the input data sets still exist.
System Access and Additional Information
Hints on using the CDAW system.
Details on data intervals,
contributing spacecraft and CDB subjects.
CDAW display and analysis system
- This allows access to all of the CDAW 6, 7, 8 and 9 data bases.
The system supports a range of graphics devices including Tektronix terminals/emulators and X-windows.
CDAW/NACS Users Guide and parameter catalogs
- for the CDAW 6, 7, 8, and 9 data bases.
A CD-ROM containing the CDAW-9 data base is available from NSSDC.
Plans for CDAW 10
CDAW 10 is tentatively planned to involve the participants
of the International Solar-Terrestrial Physics (ISTP)
program. The "Key Parameters" of this program are being
collected by the ISTP CDHF (Central Data Handling Facility)
in a standard form for use with an improved generalized
display and analysis program under development at SPDF.
