METAR & SPECI FORMAT
Example of METAR report message
METAR LZJS 071600Z AUTO CALM //// //// 25/09 Q0977=
METAR LZJS 121140Z AUTO VRB05KT //// //// 06/04 Q0965=
METAR LZJS 121220Z AUTO 22007KT 160V290 //// //// 06/03 Q0964=
...
AUTO-METAR is a message generated every 30 minutes on the hour and half hour.
Example of SPECI report message
SPECI LZJS 080925Z AUTO 22012G24KT 160V290 //// //// 07/03 Q0975=
SPECI LZJS 081039Z AUTO 22015G34KT 150V280 //// //// 08/04 Q0975=
...
SPECI report is only generated when there is a significant change or deterioration in weather conditions, and is generated when necessary, in real-time and without delay in between METAR messages.
METAR & SPECI message additional info
- METAR & SPECI report detailed format is derived from available sensors. //// are used where sensor data is unavailable.
- SPECI is an aviation special weather report issued when there is a significant deterioration or improvement in airport weather conditions such as significant changes of surface winds, visibility, cloud base height and occurrence of severe weather.
