Example #2:
METAR 191050Z 25007KT 9999 FEW025 05/M07 QI015 NOSIG 191050Z The first group of example #2 is the date and time (DTG) in UTC. The 2-digit (19) is the date of the current month and the next 4-digit (1050Z) is the time in UTC followed by the indicator Z. 25007KT The second group of example #2 is the wind direction and velocity where it is blowing from. The 3-digit (360) is the wind direction measured using the 36-points of a compass and the succeeding 2-digit is the wind velocity measure in Knots. Other European countries use Meters Per Second. 9999 This is the visibility group. Visibility is given in meters. If visibility is 10 kilometers or more, the code will be 9999. FEW025 Clouds are given in groups telling you how much of the sky is covered by clouds and how high those clouds are, given in feet. It is given in 3-digits. 2500ft will be coded as 025, 25000ft will be coded as 250. Cloud coverage of the sky is divided into 8 logical sectors. Cloud coverage is given using the following designators:
FEW: 1-2
eights coverage 03/M05 This group is the rounded figure of current temperature and dew point in degree Celsius separated by a forward slash. If the dew point temperature is below zero (0), an M will be inserted in the code. Q1015 This group is the QNH. QNH is an international code for the air pressure at the aerodrome reduced to sea level. In METAR this is prefixed with the letter Q if the QNH is given in Hectopascal (hPa), and A if the QNH is given in inches of mercury. It is always given in four digits, a QNH of 998 will then be Q0998 in a METAR. NOSIG This is a trend forecast for the next 2-hours. No Significant Change. [View full METAR report] |
