How do I decode a METAR report?
Decoding a METAR
- PHNL = the airfield, Honolulu’s Daniel K.
- 250953Z = the date and time of the report.
- 05007G17KT = the wind conditions.
- 10SM = visibility.
- FEW024 / FEW040 = cloud cover.
- 27/19 = the temperature and dewpoint.
- A3001 = the atmospheric pressure, a.k.a. altimeter setting.
What is a METAR code?
METAR is the name of the international meteorological code for an aviation routine weather report. METAR observations are normally taken and disseminated on the hour.
What does Q mean in METAR?
QNH. QNH is stated to the nearest whole hectopascal (equivalent to a millibar) rounded down and preceded by the letter Q e.g. Q1013 = QNH 1013 Hectopascals. Recent Weather.
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 are METARs and TAFs?
METAR is the international standard code format for hourly surface weather observations which is analogous to the SA coding currently used in the US. The acronym roughly translates from French as Aviation Routine Weather Report. TAF is the international standard code format for terminal forecasts issued for airports.
What is Rae in METAR?
RAE. Rain Ended @ HHMM (RAE 1433) or as Min past hour (RAE 33) [METAR] RAPID. Rapid(ly)
How long is METAR valid for?
How long is a TAF valid or updated? METAR is used to tell the actual meteorological conditions on a station, airport or area indicating day/time wind, clouds, precipitations, altimeter pressure and temperature, it has a duration of 60 minutes and it is updated every hour.
What is VV in aviation?
VV. Vertical Visibility (Indefinite Ceiling) WS. Wind shear (In TAFs, low level and not associated with convective activity)
What is Altimeter METAR?
The altimeter setting QNH is one of the data included in METAR messages from weather stations in addition to the surface pressure. QNH is the barometric altimeter setting that causes an altimeter to read airfield elevation above mean sea level when on the airfield.
What do the METAR and Taf codes mean?
METAR codes report observed weather conditions by airfield; TAF codes report forecasted weather conditions by airfield. Both codes are lines of text made up of data groups (or just “groups”) separated by spaces. Some data groups are not discussed because they are intended for use by the weather community and are not useful for flight planning.
When did Canada replace the SA with METAR?
Canada made a commitment to produce and distribute METAR reports internationally for 31 sites commencing July 31, 1993. Further to this, Canada, the United States, and Mexico have agreed to replace the SA with METAR for aviation within North America beginning in 1996.
What is the ICAO station identifier for METAR?
There is no provision in METAR for an “RS” report. An aviation weather report taken on the hour. CCCC is the 4-letter ICAO station identifier (formed by “C” preceding the Canadian 3?letter station identifier).
How is the prevailing visibility reported in METAR?
Lower sector visibilities which are half or less of the prevailing visibility are reported as remarks at the end of the report. In Canada and the U.S., the unit for reporting visibility is statute miles. Other countries report the visibility in metres. The prevailing visibility is 3/4 statute miles.
