a new (preliminary) version of the OSCAR/Surface user manual (English) is published:
https://library.wmo.int/index.php?lvl=notice_display&id=20824#.XaRg0a6Wapq .
It contains a lot of new documentation on the XML files and the OSCAR/Surface API, so check it out!
The final version including translations in all UN languages will be out soon.
