How To Decode A Metar Report Part 1 Explained By Captain Joe вђ Otosection Altimeter setting. the final section of the easy part is the altimeter setting. the “a” stands for altimeter and the number following is the altimeter setting around 55 past the hour. teaching tangent: when you do your run up, dial in the current altimeter and compare what’s in the window to the airport elevation. T11001144 is a more precise measure of the temperature and dewpoint, down to a tenth of the degree. in this case, the 1100 means the temperature is 10.0 degrees celsius. then, 1144 means a dewpoint of 14.4 degrees celsius. a preceding 1 means negative, while a preceding 0 means the temperature is above zero. 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. Metar date & time. 220136z. 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. metar modifier (if any) 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.

In the metar you will also find the air pressure at the mean sea level (qnh). this is calculated by recalculating the air pressure at terrain height (qfe) back to sea level. air pressure can be expressed in inches of mercury (preceded by an a) or hectopascals (preceded by a q). a2994 means air pressure of 29.94 inhg. A metar will always start with a 4 letter designator. this will match the four letter icao designator of the airport in question. the above metar corresponds to baltimore airport. there are actually hundreds of these icao codes used throughout the usa. why it is important in a metar – it should be obvious.
