Hourly observations from stations distributed globally resulting in around 10,000 reports a day.
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.
There are no known data issues at present.
No additional information at this time.
The table below provides the list of available parameters in the column order that they appear in the BADC-CSV files in the archive.
