METAR KTTN 051853Z 04011KT 1/2SM VCTS SN FZFG BKN003 OVC010 M02/M02 A3006

Formatul METAR - FAAMETAR indicates that the following is a standard hourly observation. KTTN is the ICAO identifier for the Trenton-Mercer Airport. 051853Z indicates the day of the month is the fifth and the time of day is 1853 Zulu/UTC, 6:53PM GMT, or 1:53PM Eastern Standard Time. 04011KT indicates the wind is from 040 true (north east) at 11 KT (20 km/h; 13 mph). In the United States, the wind direction must have a 60 or greater variance for variable wind direction to be reported and the wind speed must be 7 KT (13 km/h; 8 mph) or higher. 1/2SM indicates the prevailing visibility is 0.5 SM (800 m). VCTS indicates a thunderstorm in the vicinity (within 10SM (16 km), but beyond 5SM (8 km)). SN indicates snow is falling at a moderate intensity. If any precipitation begins with a minus or plus (-/+) it s either light or heavy (-/+), it's heavy. FZFG indicates the presence of freezing fog. BKN003 OVC010 indicates a broken cloud layer at 300 ft (91 m) above ground level and a solid or overcast layer at 1,000 ft (300 m). The last two zeros are omitted. M02/M02 indicates the temperature is 2 C (28 F) and the dewpoint is 2 C (28 F). An M in front of the number indicates that the temperature/dew point is below zero (0) Celsius. A3006 indicates the altimeter setting is 30.06 inHg (1,018 hPa)

METAR LBBG 041600Z 12003MPS 310V290 1400 R04/P1500N R22/P1500U +SN BKN022 OVC050 M04/M07 Q1020 NOSIG 9949//91=METAR indicates that the following is a standard hourly observation. LBBG is the ICAO airport code for Burgas Airport. 041600Z i di t th ti indicates the time of th observation. It i th d of th month (th 4th) f ll f the b ti is the day f the th (the followed b th ti d by the time of d (1600 Z l f day Zulu time, which equals 4:00 pm Greenwich Mean Time). 12003MPS indicates the wind direction is from 120 (east-southeast) at a speed of 3 MPS (5.8 KT; 6.7 mph; 11 km/h). Speed measurements can vary from knots (KT) or meters/second (MPS). 310V290 indicates the wind direction is varying from 310 true (northwest) to 290 true (west-northwest). 1400 indicates the prevailing visibility is 1,400 m (4,600 ft). R04/P1500N indicates the Runway Visual Range (RVR) along runway 04 is 1,500 m (4,900 ft) and not changing significantly. R22/P1500U indicates RVR along runway 22 is 1,500 m (4,900 ft) and rising. +SN indicates snow is falling at a heavy intensity. If any precipitation begins with a minus or plus (-/+), it's either light or heavy. BKN022 indicates a broken (over half the sky) cloud layer at 2,200 ft (670 m) above ground level (AGL). "BKN" or "OVC" specifies the cloud ceiling. OVC050 indicates an unbroken cloud layer ( y (overcast) at 5,000 ft ( ) (1,500 m) above g ) ground level. M04/M07 indicates the temperature is 4 C (25 F) and the dewpoint is 7 C (19 F). An M in front of the number indicates that the temperature/dew point is below zero (0) Celsius. Q1020 indicates the current altimeter setting (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. NOSIG means that no significant change is expected to the reported conditions within the next 2 hours. 9949//91 indicates the condition of the runway: 99 indicates either a specific runway (eg 25 = Rwy 25 or 25R; adding 50 will indicate Left Runway) or all the airport's runways ("99"). Some locations will report the runway using 3 characters (eg 25L) 4 means the runway is coated with dry snow 9 means 51% to 100% of the runway is covered // means the thickness of the coating was either not measurable or not affecting usage of the runway 91 means the braking index is bad, in other words the tires have bad grip on the runway
