Incoming files
Originating centres should upload their files to the FTP server ftp.ecmwf.int (using login wmolcdnv) to the directory /data/incoming/ (URL ftp://wmolcdnv@ftp.ecmwf.int/data/incoming/)
The incoming directory for incoming files will be periodically scanned and new files processed. If a new file passes the syntax check it will be moved to the archive directory and its content imported to the LC DNV score database.
Archived files
URL ftp://wmolcdnv@ftp.ecmwf.int/, directory: /data/svs/cccc/
(for the centre identifier cccc see above).
