TX – Indicator for Maximum temperature. TtTt – Temperature value in Celsius. TN – Indicator for Minimum temperature. HH – Forecast hour, i.e. the time(hour) when the temperature is expected.
What does 9999 mean in aviation?
The largest reportable metric value is 9999. This value represents a visibility greater than 9000 meters (7 SM or more).
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.
What does R88 mean?
All other METARs from UTAA today contain “R88/CLRD70 ” as well. R88/CLRD70 means: all runways are cleared (no more deposits), and a friction coefficient of 0.70.
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 the T at the end of a METAR?
The “0” after the “T” indicates that the temperature and dew point are higher than 0 degrees Celsius (a “1” will follow the “T” when the dew point temperature and /or the temperature is / are less than 0 degrees Celsius).
What does M mean in a METAR?
An M in front of the number indicates that the temperature/dew point is below zero Celsius. Q1020 indicates the current altimeter setting (in QNH) is 1,020 hPa (30.12 inHg). NOSIG is an example of a TREND forecast which is appended to METARs at stations while a forecaster is on watch.
What Does VC mean in a TAF?
“VC” = Vicinity, but not at aerodrome. In the US METAR, 5 to 10 SM from the point of observation. In the US TAF, 5 to 10 SM from the center of the runway complex.
What is NSW in a TAF?
NSW (no significant weather)
What is Br in a TAF?
The abbreviation for a condition of mist is BR on METAR and TAF reports.
What is Cor in METAR?
Presence of “COR” in a METAR means that a corrected METAR or SPECI is being transmitted. “COR” report invalidates a previous message and replaces it with a “COR” message.
What does Qnh mean on a TAF?
QNH. The QNH is the atmospheric pressure corrected to mean sea level (based on International Standard Atmosphere conditions throughout the height difference) and is reported in the METAR rounded down to the nearest whole hectopascal.
What is A02 in METAR?
A02 means that the site is automated and HAS a precipitation sensor. If it were AO1, there would be no precip sensor. This does not mean the site is un-manned. If there is an AUTO after the ID in the metar ob, then there is no observer.
Are METAR winds 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.
