The content of the international aviation data, U.S. warnings, and all types of hydrometeorological forecasts are as transmitted by the source, however, they are parsed into separate specific files using file names of a site ID or warning and forecast area designator. There is a Help Guide that shows how to access the server and retrieve the files. The set of data that are separated and stored under different sub-directories and files include all of the data types listed here. File names within each data subcategory directory use either site ICAO identifiers, zone numbers, country warning area numbers, or text names to indicate the content subject. The files are stored as quickly as they are built.
All files are over-written by new received information after being processed.
The original bulletins as transmitted on the FOS are also stored with no parsing other than by the first two characters of the heading under which is was sent. In this data set the file names are the WMO headings. Please note that these products can be very large and could take several minutes to retreive. The bulletins are received by the Gateway, passed to the server, broken-down and filed for retrieval. Data files are written only when data of that subcategory type is available.
