NOTICE: This is an automatic file transfer process and every submission will be disseminated world-wide as determined by the routing established for the WMO abbreviated heading you use in the bulletin contained in the file. The provider is responsible for the content.
File Handling Process: This portal can receive
observational and forecast product WMO bulletins as
contents of a file. The files are uploaded to the RTH using standard FTP.
After the initial account implementation is programmed and established,
file transfers can begin. All files will be automatically processed by
the RTH upon receipt. As the files contain bulletins for delivery on the
GTS, there is no additional metadata files required. The WMO bulletins
are removed from the files and immediately switched by the RTH. The received
files will be erased from the receiving file server sub directory. The
standard WMO bulletins will be handled just like they were received from
any GTS circuit. The file names can only be dupicated monthly. If the Internet
is used as the path for delivery, the RTH may not always be reachable.
FTP Input Service Rules and Definitions:
Note 1 : The "WMO
message" envelopes the "WMO bulletin" and has an end sequence called a: Ending line: [ cr ] [ cr ] [ lf ] [ETX]These two lines are not allowed in this process. |

Directory and File Name Standard
The files sent may contain one or more bulletins. Each bulletin
in the file (including the first one) must be prefixed with a flag
field to separate bulletins. The bulletin size should meet the
WMO standard to achieve switching of the bulletins onto the MTN of
the GTS.
