domain-averaged scores (

...

a.k.a. "WMO scores") please refer to the respective document.

One file shall contain scores relevant to one parameter and one month, either daily score values or monthly means. In order to reduce the data volume and facilitate the data transfer the files can be additionally compressed by one of the supported methods: GZIP (DEFLATE method), ZIP or BZIP2.

Note

Should the originating centre wish to compress the data file it is requested to liaise with LCDNV to verify LCDNV can handle the chosen compression method.

The format of the files is described here.

Pattern for file names

yyyymm _ cccc _monthly.xxx (for monthly means) yyyymm_cccc_daily.xxx (for daily values) PARAM .svs[. zzz ]
where:
yyyymm is year and month of the calendar month data are relevant for;
cccc is the 4-character WMO identifier of the originating centre
(ammc=Melbourne, cwao=Montreal, dems=New Delhi, ecmf=ECMWF, edzw=Offenbach, egrr=Exeter, kwbc=Washington, lfpw=Toulouse, rjtd=Tokyo, rksl=Seoul, rums=Moscow, ...);
xxx PARAM is the suffix string identifying the format:
"asc" if the file is in the current format of ASCII tables exchanged by e-mail
"rec" if the file is in the new format and contains scores computed by the old rules
"rec2" if the file is in the new format and contains scores computed by the new rules (from 2011)parameter:

Incoming files

Originating centres should upload their files to the FTP server ftpaux.ecmwf.int (using login wmolcdnv) to the directory /data/incoming/ (URL ftp://wmolcdnv@ftpwmolcdnv@aux.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 ftpsftp://wmolcdnv@ftpwmolcdnv@aux.ecmwf.int/, directory:
/data/monthlysvs/cccc/ (for monthly means)
/data/daily/cccc/ (for daily values)
(for the centre identifier cccc see above).
Note the preferable transfer protocol is SFTP, although the plain FTP can be also used. For information on how to get access to FTP server please check here.
