sign), heavy (+); FG: fog; FZFG: freezing fog (temperature below 0°C); BR: mist; HZ: haze; SQ: squall; maximum of three groups reported; augmented by observer: FC (funnel.

Is METAR wind true or magnetic?

Is the wind magnetic or true in the METAR/TAF reports? METAR winds are true and ATIS winds are magnetic, except Digital ATIS.

What does 9999 mean in METAR?

The largest reportable metric value is 9999. This value represents a visibility greater than 9000 meters (7 SM or more). To convert visibility values from meters to statute miles see Attachment 3 on page 33 or see Flight Information Handbook conversion tables. 8. METAR.

What is the 5 * * * * Group on a METAR?

pressure tendency
53018 indicates the pressure tendency (the “5 group”). The digit following the “5”, which can vary from 0 to 8, describes the behavior of the pressure over the past three hours (for guidance, consult the table below). The last three digits represent the amount of pressure change in tenths of a millibar.

Are Metars in AGL or MSL?

Remember, METAR and TAF report the height of clouds AGL, not MSL.

How do you decode Metars and TAFs?

The first three digits are the true direction to the nearest 10 degrees from which the wind is blowing. The next two digits are the sustained speed. If gusts are present, the next two or three digits following the “G” are the “gust,” the maximum wind speed in the last ten minutes.

How do I read METAR data?

The first two digits are the date, the 16th of the month, and the last four digits are the time of the METAR, which is always given in coordinated universal time (UTC), otherwise known as Zulu time. A “Z” is appended to the end of the time to denote that the time is given in Zulu time (UTC) as opposed to local time.

What is SLP in METAR?

Let’s take a look at what these abbreviations represent, starting with the “SLP” notation that comes after any comments in the “remarks” section of a METAR: SLP stands for sea-level pressure, with the pressure expressed in millibars. The reading is abbreviated. “SLP201” translates to 1,020.1 millibars.

Are METAR clouds AGL or MSL?

How is wind reported in a METAR?

Wind direction – coded as the first three digits (090), determined by averaging the recorded wind direction over a 2-minute period. It is coded as tens of degrees relative to true north. Directions less than 100 degrees are preceded with a 0. For example, a wind direction of 90 degrees is coded as 090.

What does 8000 mean in a TAF?

GROUP 4: Visibility, Weather, and Obstructions to Vision:

What does 9999 mean on METAR?

Visibility. Reported in a four figure group (e.g. 0400 = 400 metres; 8000 = 8 km) up to but excluding 10 km; 9999 = 10km or more; 0000 = less than 50 metres visibility.

What does 6 mean in a METAR?

The preface of a “6” indicates rainfall, in 0.01″, in the past six hours. “60000” indicates a trace of precipitation, so “6////” is used to indicate no rain at all.

Are METARs and TAFs AGL?

TAF’s and METAR’s are always AGL. Area Forecasts (FA) are always MSL unless the height is specifically tagged AGL or CIG (for “ceiling”). It may seem annoying that FA’s are MSL, but they cover large areas where the terrain may vary but the clould bases are usually at a constant height MSL.

What does 9999 mean in a METAR?
