Metar

Introduction Meteorological messages contain informations about weather observations and weather forecasts, coded according to specific rules issued by World Meteorological Organization (WMO).First of all they are divided in 'synoptics' messages (code SYNOP and TEMP), and 'aeronautic' messages (METAR e TAF). First ones contain meteorological observation at ground and altitude respectively, taken at synoptic hours or in hours during which in all the stations of the world synoptic network the same observations are made with the same formalities and are coded according to the same standards; these messages are diffused all over the world through a dedicated data transmission network called Global Telecommunication System (GTS so that all information contained in it can be used from meteorological centres, mainly to initialise numerical models. On the contrary, aeronautic messages are used for assistance to air navigation: METAR contains weather observations about airports, while TAF contains weather forecasts. They too are coded, but not necessarily diffused on GTS.
