T02940167 gives us more accurate temperature and dew point information: Temperature of 29.4✬ and dew point of 16.7✬. (A great explanation of SLP by David Werntz can be found here). SLP112 tell us the sea level pressure in millibars – in this case 10 11.2mb. In this case AO2 tell us this METAR was recorded by an automatic station with a precipitation discriminator. RMK (Remarks): The remarks section can contain a number of different items.In this case, setting 29.88 on the altimeter when at the gate in Chicago will show 668 feet (i.e. Sea level pressure: A2988 Refers to an altimeter setting in inches of mercury which will show QNH (i.e.The dew point is also reported in degrees celsius. Temperature and dew point: 29/17 The temperature is reported first (in degree celsius) followed by the dew point (the temperature at which the air would become saturated with water vapor).Cloud cover: FEW250 refers to few cloud at 25,000 feet.Ĭloud cover is measured in “Oktas” or “eighths of the sky”.īroken (BKN) = 5-7 Oktas (i.e.10SM is a visibility of “10 Statute Miles or greater”). visibility is measured in Statute Miles (SM) and feet. In this case the wind is from 260º True, at 14 knots.
Wind speed is normally issued in knots, but can also be issued in “MPS” (meters per second). with reference to true north, as opposed to magnetic north).
