CDAS Web Services
The Coordinated Data Analysis System (CDAS) Web services allow a software
developer to use CDAS services in their own application. If you are
not a software developer and simply want to use the existing web (HTML)
interface to CDAS, then return to the
main CDAWeb page.
CDAS supports simultaneous multi-mission, multi-instrument selection and
comparison of science data among a wide range of current space missions.
While CDAWeb provides access to this data through an HTML-based user interface,
these Web services provides a
application programmming interface
(API) to CDAS. If you are developing an application that requires
science data from any of the data sets held by CDAS, then the CDAS Web
services will provide an interface to the data for your application.
