Code SYNOP
Sign in to saveAlso known as surface synoptic observations, international synoptic number, FM-12
SYNOP (surface synoptic observations) is a numerical code (called FM-12 by WMO) used for reporting weather observations made by staffed and automated weather stations. SYNOP reports are typically sent every six hours by Deutscher Wetterdienst on shortwave and low frequency using RTTY. A report consists of groups of numbers (and slashes where data is not available) describing general weather information, such as the temperature, barometric pressure and visibility at a weather station. It can be decoded by open-source software such as seaTTY, metaf2xml or Fldigi.

Le code SYNOP, ou synoptique, est un codage de données, adopté par l’Organisation météorologique mondiale, et employé pour diffuser par radiotélétype (Deutscher Wetterdienst), ou autre moyen, les observations d'une station météorologique terrestre, à intervalles réguliers de 3 heures (débutant à 0 h UTC), dites synoptiques. Le code est formé par groupes de cinq chiffres, et transmis internationalement. Environ trente-mille stations météorologiques échangent des données par ce format.
