Observing Programmes with an international system for assigning station identifiers Issuer of Identifier Category of station identifier Method of allocating Issue Number Method of allocating Local Identifier 20000 World Weather Watch land station with sub-index number (SI) = 0 0: station defined in WMO-No. 9 Volume A on 1 July 2016. Any positive number: to distinguish between different observing facilities that used the station identifier in the past. Use the block number (II) and the station number (iii) as a single five digit number IIiii (with leading zeroes). Example: station 60351 would be represented by 20001 Weather Watch land station with sub-index number (SI) = 1 0: station defined in WMO-No. 9 Volume A on 1 July 2016. Any positive number: to distinguish between different observing facilities that used the station identifier in the past. Use the block number (II) and the station number (iii) as a single five digit number IIiii (with leading zeroes). Example: upper air station 57816 would be represented by 20002 World Weather Watch Marine Platform (moored or drifting buoy, platform, etc.) 0 - platform for which the identifier was in use on 1 July 2016. Any other positive number - to distinguish Use the region/platform number combination A1bwnbnbnb Examples: the data buoy 59091 would be represented by
