What does Qnh mean in a TAF?
sea level
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. Some aerodromes report the QNH pressure in the METAR in inches of mercury.
How long is METAR valid for?
The METAR only gives you a small snapshot in time. They are only good for an hour. They are usually refreshed around 55 past the hour. TAFs, on the other hand, cover a 24 to 30 hour period and they are published 6 times a day (0000, 0600, 1200, 1800).
What does Volmet stand for?

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 P before M1 mean on a METAR?
So, if you see a “M1/4SM” it means the visibility is less than 1/4 statute miles. You may also see a “P” before the number. Today in Portland, the TAF says “P6SM.”
When was the METAR format introduced to the world?
The METAR format was introduced 1 January 1968 internationally and has been modified a number of times since. North American countries continued to use a Surface Aviation Observation (SAO) for current weather conditions until 1 June 1996, when this report was replaced with an approved variant of the METAR agreed upon in a 1989 Geneva agreement.
What does the METAR say in Portland Oregon?
Portland’s METAR will say “-RA” even when it’s pouring. So, be careful when you see the “-” and treat it with healthy skepticism. The absence of a “-” or “+” means moderate intensity. The “+” should certainly give you serious pause. It takes a lot to get a “+” on the METAR.
