If you are looking for the procedures of posting the upper-air 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.
The format of the files is described here.
Pattern for file names
yyyymm_cccc_PARAM.svs
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, ...);
PARAM is the string identifying the parameter:
PARAM | meaning |
---|---|
t2m | air temperature at 2 meters above the model orography |
td2m | dewpoint at 2 meters above the model orography |
rh2m | relative humidity at 2 meters above the model orography |
tp06 | total precipitation accumulated over previous 6 hours |
tp24 | total precipitation accumulated over previous 24 hours |
ff10m | wind speed at 10 meters above the model orography |
dd10m | wind direction at 10 meters above the model orography |
tcc | total cloud cover |
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).
