NWS eMail Data Input System (EDIS) - Operational

ISCS FTP Service (SSL VPN) - Operational

The ISCS Program Office has initiated a new service for transmitting meteorological data to the RTH-Washington as a replacement for the NWSTG FTP service on ISCS.

New ISCS File Transfer Service (FTPS)

The ISCS Program Office, in support of the international community of RA-IV Member States and other associated users, has initiated a new service for transmitting meteorological data to the Regional Telecommunications Hub (RTH)-Washington. The new FTPS adds support for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) cryptographic protocols that provides the added security. Member States may continue to use the RTH-Washington Email Data Ingest System (EDIS) as a backup service.

RTH-Washington will provide to Member States, at no cost, client software required for the transmission interface to the RTH FTPS server. Member States will have responsibility for all costs associated with maintaining a local Internet service to permit the FTPS connection.
