BUOY - Report of a drifting or moored buoy observation
Organization of the file :
------------------------
Each data line contains 33 fields, separated by spaces. The contents and sizes
of the 33 fields that appear in each data record are as follows (Unit for Unit
or Code table (from the Manual oncodes (WMO-No. 306), International codes
volume I.2, part B), Form for FORTRAN Format, Miss for Missing value) :

Data quality flags can take one of the following values :
automatic quality control procedures: 0=good 1=suspect 2=bad 3=not controlled
manually added flags: 5=good 6=suspect 7=bad 8=estimated 9=not controlled
Quality control procedures are explained in the document GTS_QC_handbook.ps that
can be found on the FASTEX anonymous ftp serveur (cnrm-ftp.cnrm.meteo.fr), in
the directory pub-fastex/doc
