The Coordinated Data Analysis Workshop Web (CDAWeb) is a web-based service that facilitates access to a scientific data base of the International Solar-Terrestrial Physics (ISTP) program and other programs that generate public scientific information. In this data base, physical-science parameters from diverse international sources are stored in the Common Data Format (CDF) standard developed by the National Space Science Data Center (NSSDC).

CDAWeb Assists the User in obtaining scientific data that have been stored in a prescribed format.

The data of the ISTP program and the CDAWeb service are parts of NASA's contribution to the Solar-Terrestrial Science Initiative of the Inter-Agency Consultative Group (IACG), a multinational space-science coordinating group. Under the auspices of IACG, CDAWeb mirror sites have been established at the Equator-S science center at the Max-Planck Institute in Garching, Germany, and at the Rutherford Appleton Laboratory in the United Kingdom.

CDAWeb is built using standard software packages. The "engine" of CDAWeb is a set of scripts in the Interactive Data Language (IDL) of Research Systems Inc. (RSI). CDAWeb also includes web-page software components and common gateway interface (CGI) scripts that act as interfaces between the IDL scripts and the user, plus supporting software utilities to create the metadata data-base files used by the interface scripts. The CDAWeb software package for mirror sites does not include IDL, which is a commercial product that must be obtained separately.

This work was done under the direction of Robert E. McGuire of Goddard Space Flight Center . For further information, access the CDAWeb service at or the Technical Support Package (TSP) free on-line at  under the Information Sciences category. GSC-14292
