Met Office - metDB Data: ship SYNOP data

Brief description

SYNOP message from sea based stations (ships, rigs, platforms and moored buoys) using WMO code FM 13-X.

Observation coverage

Hourly observations from stations distributed globally resulting in around 10,000 reports a day.

Delivery and ingest schedule

Data are extracted for the 4 principal synoptic periods (00-06, 06-12, 12-18 and 18-00 UT) and delivered to the BADC at the following times (all in GMT):

Synoptic period Delivery to BADC
0000-0559 1330
0600-1159 1930
1200-1759 0130
1800-2359 0730

Ingest scripts run at the BADC every 20 minutes, converting the incoming files to the self describing BADC-CSV format, but neither the processed or raw data are placed into archive until the following day.

Known problems

There are no known data issues at present.

Additional information

No additional information at this time.
