and oceanographic data
Instructions for the proper application of the level designators


(1)  This table is subdivided into two parts: Part I contains geographical designators related to countries or territories in each RTH zone of responsibility for the collection of observational reports (surface and upperair); Part II contains those for vast areas such as continents, hemispheres, etc.
(2) In the case of bulletins containing observational reports (surface and upper-air) from land stations, geographical designators contained in Part II of the table should be used only when no suitable designators are available in Part I of the table.
(3) In the case of bulletins containing meteorological information related to aircraft reports, analyses, prognoses, warnings, climatological data, satellite data and also analogue facsimile information, all the geographical designators contained in this table can be used. However, as far as possible, the geographical designator XX should not be used.
(4) For the geographical designator in the abbreviated heading of the METNO and WIFMA messages, XX should be used.
(5) Geographical designators contained in this table should not be used in the abbreviated heading of bulletins containing ships’ weather reports and oceanographic data.
(6) For T1T2=SZ A1A2 area designator from Table C1 should be used.
