The color chart shown above, shows the usage of all SPDF services.

The numbers graphed represent actual executions of the system delivering products. For easier comparison to the statistics of other Web-based services, the total number of Web page "hits" and files retrieved from the system by month is also shown (normalized to a 1/10th scale).

CDAWeb is a joint effort among the Space Physics Data Facility (SPDF), the National Space Science Data Center (NSSDC) and the ISTP project and its Science Planning and Operations Facility (SPOF). CDAWeb is most easily accessed at the URL or via that of SPDF (
