SYNOP Data Format (FM-12) Surface Synoptic Observations | Agrisemantics Map of Data Standards

PLEASE HELP US BY COMPLETING A QUICK SURVEY ON THE USE OF THIS MAP: click here

SYNOP (surface synoptic observations) is a numerical code (called FM-12 by WMO) used for reporting weather observations made by manned 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.
