Predictions Availability

Predictions data is available daily via either anonymous ftp or the web from the global data centers (CDDIS, EDC). NSGF predicts are also available via anonymous ftp or the NSGF web site. In addition, daily predicts are available via email. If you would like to be added to the predictions distribution list contact Carey Noll (carey.noll@nasa.gov).

Below is a table of Centers who archive predictions along with accessibility information (i.e., node names, IP addresses, URLs, directory structure, filenaming conventions, and point of contact).
