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 is RMK in Metar?
RMK simply means REMARKS and marks the end of the standard metar observation and the beginning of the remarks that are put in as necessay. If there is an AUTO after the ID in the metar ob, then there is no observer.
What is Metar and TAF?
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 Cor in Metar?
COR indicates a corrected observation. Disregard the previous transmission. COR 1725 means that the correction was transmitted at 1725Z. 5. METAR.

|M||IN TEMPERATURE FIELD MEANS “MINUS” OR BELOW ZERO (METAR)|
|M||IN RVR LISTING INDICATES VISIBILITY LESS THAN LOWEST REPORTABLE SENSOR VALUE|
|M||MISSING (WEATHER REPORTS ONLY)|

What does CIG mean in aviation?
CHINO. sky condition at secondary location not available. CIG. ceiling.
What does PK WND mean?
PK WND 20032/25 PEAK WIND. PK WND dddff(F)/(hh)mm; direction in tens of degrees, speed in whole knots, time in minutes after the hour. Only minutes after the hour is included if the hour can be inferred from the report.
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 is Cor aviation?
A COR is a preplanned route of flight that can be rapidly issued, coordinated, and communicated to pilots, controllers, and FM automation systems: The COR route database provides a quick alternative to developing an alternate route at the time a system constraint occurs.
What is the T at the end of a Metar?
What is CFS model?
The Climate Forecast System (CFS) models the interactions between Earth’s oceans, land, and atmosphere on a global scale.
What do the numbers mean in METAR?
The first two digits 22 refers to the day of the month. The next 4 digits 0136 refers to the time when the report was made. The Z refers to ZULU or UTC time. Sometimes the METAR will have a COR or AUTO modifier after the Date & Time. COR means it is a corrected report and AUTO refers to an automated station.
What does Cor mean on a METAR report?
Sometimes the METAR will have a COR or AUTO modifier after the Date & Time. COR means it is a corrected report and AUTO refers to an automated station. The first three digits 310 is the direction of the wind in degrees. The second numbers 06 mean refer to the wind speed in knots. KT means knots.
What is the difference between METAR and SPECI?
A SPECI is identical to a METAR with the difference that it is not created regularly but from time to time. It is a special observation message showing a punctual meteorological event that occurred since the last METAR or SPECI published. The issuance of a SPECI is not necessary if METAR are issued at half-hour intervals.
How is visibility information reported in METAR?
In METAR, visibility observations should be representative of the aerodrome. In such observations, special attention should be paid to significant directional variations in visibility. The visibility information is reported in steps of 50 m when visibility is less than 800 m;
