Met Report is a format for reporting weather information that contain all data related to the runway in use and it can be sent every hour or every 30 minutes. If there are weather change between the bulletins, AMO employees must send another bulletin called SPECIAL.

• Prevailing Visibility
• Runway Visual Range ( this data is posted if the prevailing visibility is under 1500 meters or if the visibility of one or all RVR sensors give a visibility under 1500 meters )  
• Present Weather ( the following table don't have all PW but only the most common )
