    Data Type Hierarchies

    Level 3 Data Type hierarchies vary significantly across data types (e.g. different for observations and NWP), and will be built gradually following the requirements of WMO domains.

    Each WMO domain will also define filename conventions (basename, extension)

    Shall we make a topic structure directly with GTS headers (T/T/A/A/ii/CCCC )?
